To solve an application, we’ll first translate the words into a system of linear equations. Then we will decide the most convenient method to use, and then solve the system. Solve applications with systems of equations. Read the problem. Make sure all the words and ideas are understood. Identify what we are looking for.

How to solve algebra problems?
Translate into an equation. It may be helpful to restate the problem in one sentence with all the important information. Then, translate the English sentence into an algebra equation. Solve the equation using good algebra techniques. Check the answer in the problem and make sure it makes sense.
How to solve linear algebraic equations?
Solve a basic linear algebraic equation. A linear algebraic equation is nice and simple, containing only constants and variables to the first degree (no exponents or fancy stuff). To solve it, simply use multiplication, division, addition, and subtraction when necessary to isolate the variable and solve for "x".
How do you know if an equation has been simplified?
Look at the coefficients of all of the terms (the numbers before the variables, or the constants) and see if there is a number that you can "factor out" by dividing each term by that number. If you can do this, then you have simplified the equation and are on your way to solving it. Here's how:
How do you solve a problem in one sentence?
We’ll start by restating the problem in just one sentence, assign a variable, and then translate the sentence into an equation to solve. When assigning a variable, choose a letter that reminds you of what you are looking for. The Robles family has two dogs, Buster and Chandler. Together, they weigh 71 71 pounds. Chandler weighs 28 28 pounds.

4.2.1 Solve Direct Translation Applications
Systems of linear equations are very useful for solving applications. Some people find setting up word problems with two variables easier than setting them up with just one variable. To solve an application, we’ll first translate the words into a system of linear equations.
4.2.2 Solve Geometry Applications
We will now solve geometry applications using systems of linear equations. We will need to add complementary angles and supplementary angles to our list some properties of angles.
4.2.3 Solve uniform motion applications
We used a table to organize the information in uniform motion problems when we introduced them earlier. We’ll continue using the table here. The basic equation was D = r t where D is the distance traveled, r is the rate, and t is the time.
What is the markup on a calculator?
First, let’s define p p to be the cost that the store paid for the calculator. The stores markup on the calculator is 15%. This means that 0.15 p p has been added on to the original price ( p p) to get the amount the calculator is being sold for. In other words, we have the following equation
How to calculate distance a car travels?
We used the standard formula here twice, once for each car. We know that the distance a car travels is the rate of the car times the time traveled by the car. In this case we know that Car A travels at 100 mph for t t hours and that Car B travels at 70 mph for t t hours as well. Plugging these into the word equation and solving gives us,
How many gallons of 50% solution to get 40%?
So, we need 5 gallons of the 50% solution to get a 40% solution.
How far does the distance car A travels plus the distance car B travels?
From this figure we can see that the Distance Car A travels plus the Distance Car B travels must equal the total distance separating the two cars, 500 miles.

Shayla paid $24,575 $24,575 for her new car. This was $875 $875 less than the sticker price. What was the sticker price of the car?
How to solve an algebraic equation?
If you want to solve an algebraic expression, first understand that expressions, unlike equations, are mathematical phrase that can contain numbers and/or variables but cannot be solved. For example, 4x + 2 is an expression. To reduce the expression, combine like terms, for example everything with the same variable. After you've done that, factor numbers by finding the lowest common denominator. Then, use the order of operations, which is known by the acronym PEMDAS, to reduce or solve the problem. To learn how to solve algebraic equations, keep scrolling!
How to solve an equation with exponents?
If the equation has exponents, then all you have to do is find a way to isolate the exponent on one side of the equation and then to solve by "removing" the exponent by finding the root of both the exponent and the constant on the other side. Here's how you do it:
What is the difference between algebraic expression and algebraic equation?
Understand the difference between an algebraic expression and an algebraic equation. An algebraic expression is a mathematical phrase that can contain numbers and/or variables. It does not contain an equals sign and cannot be solved. An algebraic equation, however, can be solved, and does include a series of algebraic expressions separated by an equals sign. Here are some examples:
How to solve an algebraic expression with fractions?
If you want to solve an algebraic expression that uses fractions, then you have to cross multiply the fractions, combine like terms, and then isolate the variable. Here's how you would do it: (x + 3)/6 = 2/3. First, cross multiply to get rid of the fraction.
How to solve linear algebra?
A linear algebraic equation is nice and simple, containing only constants and variables to the first degree (no exponents or fancy stuff). To solve it, simply use multiplication, division, addition, and subtraction when necessary to isolate the variable and solve for "x".
How to find absolute value of a number?
So, for example, the absolute value of -3 (also known as |3|), is simply 3. To find the absolute value, you have to isolate the absolute value and then solve for x twice, solving both for x with the absolute value simply removed, and for x when the terms on the other side of the equals sign have changed their signs from positive to negative and vice versa . Here's how to do it:
What is algebraic expression?
Algebraic expressions are a quick way to represent somewhat complicated situations that may occur in real life. They are a "shorthand" approach to tangible problems that might arise.
