Answer:

x = 14 thus D)

Explanation:

Solve for x:

3 x - 6 = 2 (x + 4)

Expand out terms of the right hand side:

3 x - 6 = 2 x + 8

Subtract 2 x from both sides:

(3 x - 2 x) - 6 = (2 x - 2 x) + 8

3 x - 2 x = x:

x - 6 = (2 x - 2 x) + 8

2 x - 2 x = 0:

x - 6 = 8

Add 6 to both sides:

x + (6 - 6) = 6 + 8

6 - 6 = 0:

x = 8 + 6

8 + 6 = 14:

Answer: x = 14
