Answer 2

The correct answer is "x = -5". Further explanation is given below.

Step-by-step explanation:

The given equation is:

3(x+2) = x-4

On evaluating the above equation, we get

⇒  3x+6 = x-4

On subtracting "6" from both sides, we get

⇒  3x+6-6 = x-4-6

⇒  3x = x-10

On subtracting "x" from both sides, we get

⇒  3x-x = -10

⇒  2x = -10

⇒  x = $\frac{-10}{2}$

⇒  x = -5
