Introduction: Solving 3x + 2 = 8

In this Instructible, I will show you how to solve the equation 3x + 2 = 8.

Step 1: Step 1: Subtract

The first step is to subtract 2 from both sides of the equal sign:

3x + 2 = 8
       -2   -2

Which leaves us:
3x = 6

Step 2: Step 2: Divide

In Step 2, we divide both sides by the coefficient in front of x:

3x = 6
  /3    /3

Which gives us:

x = 2

Step 3: Step 3: Check Your Solution

In the final step, we will check our solution by plugging our answer back in to the original equation:

3(2) + 2 = 8

We simplify this according to PEMDAS

6 + 2 = 8
8 = 8

Since we get the same number on both sides, we know the solution x = 2 is correct!
