Step-by-step explanation:

Step 1: Define

Identify

5(x + 2) = 6x + 3x - 14

Step 2: Solve for x

[Addition] Combine like terms: 5(x + 2) = 9x - 14
[Distributive Property] Distribute 5: 5x + 10 = 9x - 14
[Subtraction Property of Equality] Subtract 9x on both sides: -4x + 10 = -14
[Subtraction Property of Equality] Subtract 10 on both sides: -4x = -24
[Division Property of Equality] Divide -4 on both sides: x = 6
