Step-by-step explanation:

Step 1: Define

8 = 2x + 4

Step 2: Solve for x

[Subtraction Property of Equality] Subtract 4 on both sides:                        4 = 2x[Division Property of Equality] Divide 2 on both sides:                                  2 = xRewrite:                                                                                                             x = 2
