Solving TwoStep Equations Page 1 of 4 Accompanying Resources: Boom Cards, Fun Activity, Assessment, Google Drive Activity Review: OneStep EquationsIn order to understand how to solve a twostep equation, it's important that you first understand how to solve a onestep equation (check out the lesson if you need a refresher!). When solving an equation, the goal is to get the variable by itself. In a onestep equation, you use the inverse operation to do this.
Addition and subtraction are inverses  they can cancel out what the other one has done. Multiplication and division are also inverses  they can cancel each other out as well. Let's look at one quick example: 4 is being subtracted from the variable x. How do we get x by itself? To undo subtraction, we need to use the inverse of subtraction: addition. To cancel out the minus 4, we need to add 4 to both sides. Remember to always do the same thing to BOTH sides of the equation when solving so that you keep things balanced. It's pretty easy to check your answer. Plug 17 in for x in the original equation. Does 17  4 equal 13? Yes, this means you have the right answer. Make sure to check out the lesson on solving onestep equations if you need extra review. Go to the next page if you're ready for an equation with 2 steps.
