## Introduction

In our previous lesson, we covered solving 1 step algebraic equations. Well, in this lesson, we will be covering the same concept except we will be dealing with 2 step equations. Let's take a look at an example!## Solving 2 Step Equations

Let's say that we have the following equation:2y + 3 = 15

In order to solve any 2 step equation, you will always do addition/subtraction first. Then you will do multiplication/division.

So, first we will subtract 3 since we have +3 is our equation:

2y + 3 = 15

- 3 = - 3

2y = 12

Now, we will divide by 2 because we have 2 times y in our equation:

2y + 3 = 15

- 3 = - 3

__2y__=

__12__

2 = 2

y = 6

## Checking your Answer!

To make sure that your answer is correct, you can always replace the variable with the answer then solve to get the answer!2y + 3 = 15

y = 6

2 x 6 + 3 = 15

12 + 3 = 15

15 = 15
