What are the 4 ways to solve linear equations?
To solve a linear equation with fraction, follow these steps: Step 1: Make any complex fraction into a simple fraction. Step 2: Find the LCM of all denominators. Step 3: Multiply the equation with the LCM of the denominator. Step 4: Cancel out the fractions as all the denominators can be divided by the LCM value.

How to clear a fraction from an equation?
To clear a fraction from an equation, multiply all of the terms on both sides of the equation by the fraction’s denominator. For example, to clear the 2 2 2 from the fraction in 5 x + 1 / 2 = 1 2 5x+1/2=12 5 x + 1 / 2 = 1 2, multiply the equation by 2 2 2 on both sides.
How to get rid of a fractional coefficient?
To get rid of a fractional coefficient, we have to multiply both sides by its reciprocal, because that’ll make the fraction 1 1 1. If you have a fractional coefficient and another term, you can isolate the term with the variable and then multiply both sides by the reciprocal of the fractional coefficient.
How to determine if a number is a solution?
Determine whether a number is a solution to an equation.#N#Substitute the number for the variable in the equation.#N#Simplify the expressions on both sides of the equation.#N#Determine whether the resulting equation is true. If it is true, the number is a solution. If it is not true, the number is not a solution.
What is the division property of equality?
As we saw in Solve Equations with the Subtraction and Addition Properties of Equality and Solve Equations Using Integers; The Division Property of Equality, a solution of an equation is a value that makes a true statement when substituted for the variable in the equation. In those sections, we found whole number and integer solutions to equations. Now that we have worked with fractions, we are ready to find fraction solutions to equations.
What to do if the number is not true?
If it is not true, the number is not a solution. Change to fractions with a LCD of 10. Subtract. Since does not result in a true equation, is not a solution to the equation. Subtract. Subtract. Since does not result in a true equation, is not a solution to the equation.
Example 2 - Equations with Fractions with the Same Denominator
Did you notice how multiplying by 2 (the denominator of both fractions) allowed us to get rid of the fractions? This is the best way to deal with equations that contain fractions.
Example 3 - Equations with Two Fractions with Different Denominators
Yes, the equations are getting harder, but if you take it step-by-step, you will arrive at the correct solution. Keep at it - I know you'll get it!
What is the goal of solving two step equations?
The main goal of solving two-step equations is to do the opposite of whatever you see until the variable on its own. Don't forget that whatever you do, you must do on both sides of the equation.
How to add 1/4 to both sides of a constant?
Starting with the constant term (the one without the variable) on the same side of the equal sign as the variable term, do the opposite of the operation used to both sides. Since the constant term (1/4) is being subtracted from both sides, you should add 1/4 to both sides.
When you add fractions, do you find the common denominator?
The common denominator for and is . becomes when you multiply both the numerator and the denominator by . Similarly, becomes when you multiply both the numerator and the denominator by .
How to find the lowest common denominator?
Possible Answers: Correct answer: Explanation: Once you've isolated x, it's important to find the lowest common denominator so that you can add the two fractions you're working with. Step 1: Isolate x and convert fractions so that they have a common denominator. Step 2: solve for x. Report an Error.
What is cross multiplication?
Correct answer: Explanation: Cross multiplication is a short-cut that comes from multiplying by the denominators on both sides of an equation. Broken down, it works like this: The 4's on the left side of the equation cancel out. Now, do the same with the denominator on the right side. The 's on the right cancel out.
