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
