How do you solve inequalities with variables on both sides?
The general rules for solving inequalities are:
- Determine operations that will isolate the variable
- Do the same operation to both sides of the inequality
- Perform the operation to the entire formula
- Variables with the same root can be combined (for example if both variables are squared)
- When multiplying (or dividing) by a negative number, switch the sign

Solve Linear Equations with Variable on both Sides
Add 45 to both the sides . 35x – 45 + 45 = 25 + 45 . 35x = 70. Divide 35 on both the sides . x = 2 . Example 2. Solve for x: 22 – 32x = 33 + x. Solution:
Solving equations with variables on both sides of the equation
When you need to solve equations with variables on both sides of the equals sign, make sure to move all the variables to one side of the equation together. A simple saying that may help you remember this is “get all your x’s to Texas.” In other words, you need to move all the x terms so that they’re

How to solve fractions with only one side?
The general rule for solving equations with fractions — whether it be only on one side or both — is to try to get rid of all of them. The most common way to find the lowest common multiple (LCM) of all of the fractions , and then multiply the LCM on both sides of the e quations.
Who created the equation "3/4"x + 2"?
Sal solves the equation (3/4)x + 2 = (3/8)x - 4. Created by Sal Khan and Monterey Institute for Technology and Education.
Can you add videos to your watch history?
Videos you watch may be added to the TV's watch history and influence TV recommendations. To avoid this, cancel and sign in to YouTube on your computer.
How to solve for y and x?
You solve for either variable in terms of the other variable (meaning that y will be equal to some expression with x in it, or that x will be equal to some expression with y in it). In this problem you could start by subtracting 9 from both sides of the equation, giving you 3y = 9x - 27. Then to solve for y, divide both sides of the equation by 3. To solve for x instead, first add 27 to both sides of the equation and then divide by 9.
How to move constants to one side of equation?
To move the constant to one side, add or subtract from each side of the equation to cancel the term on one side .
How to solve for the remaining variable?
Solve for the remaining variable. To do this, plug the value of the variable you already solved into one of the equations. This will give you an equation with only one variable. Solve for the variable using the rules of algebra. You can use either equation to solve for the remaining variable.
How to solve for an isolated variable?
Substitute the value of the isolated variable into the other equation. Make sure you substitute the entire expression for the variable. This will give you an equation with only one variable, allowing you to solve for the variable.
How to cancel a variable in math?
Cancel the variable on one side of the equation. To cancel the variable, complete the opposite operation as stated in the equation. For example, if the term is subtracted in the equation, cancel it by adding. If the term is added in the equation, cancel it by subtracting.
How to cancel coefficients?
Cancel the variable’s coefficient. To do this, perform the operation opposite from the one denoted in the equation. Usually this will mean dividing to cancel a coefficient being multiplied by a variable. Remember that whatever you do to one side of the equation, you must do to the other side of the equation as well.
How to multiply 32y?
Multiply both sides of the equation by 32y (the product of the two denominators). Thus, (2/y) (32y) = (y/32) (32 y). Perform the multiplications, so that 64 = y², and y = +/- 8. Either answer works.
