Step-by-step explanation:

Step 1: Define

3(x + 5) = 5x + 7

Step 2: Solve for x

1. [Distributive Property] Distribute 3:                                                                 3x + 15 = 5x + 7
2. [Subtraction Property of Equality] Subtract 3x on both sides:                      15 = 2x + 7
3. [Subtraction Property of Equality] Subtract 7 on both sides:                        8 = 2x
4. [Division Property of Equality] Divide 2 on both sides:                                  4 = x
5. Rewrite:                                                                                                             x = 4
