Solving Multi Step Equations
It can be difficult to understand solving multi step equations, but after learning how to solve one step and two step equations this is the final step in learning how to solve for a variable. Solving multi step equations is an important skill that involves using additive and multiplicative inverses and the variable that makes the equation true.

How to solve multi-step linear equations?
Goal: Isolate the variable on one side of the equation.
1. Clear fractions or decimals
2. Clear parenthesis
3. Get the variable terms on one side
4. Undo addition or subtraction
5. Undo multiplication or division
