Simplify your answer as much as possible.
X =

Answer 1

X=5

Explanation:

Step 1: Define

Identify

2(3x - 7) = 16

Step 2: Solve for x

1. [Division Property of Equality] Divide 2 on both sides: 3x - 7 = 8
2. [Addition Property of Equality] Add 7 on both sides: 3x = 15
3. [Division Property of Equality] Divide 3 on both sides: x = 5
