All you have to do is simplify the equation, then isolate x to find its value:

2 - 3 ( x + 4 ) = 8

- 3 ( x + 4 ) + 2 = 8

- ( 3x + 12 ) = 2 = 8

-3x - 12 + 2 = 8

-3x - 10 = 8

-3x = 18

x =
(18)/(-3)

x = -6

The answer is A= -6

Hope that helps!

2-3(x+4)=8\qquad|\text{use distributive property}\\\\2+(-3)(x)+(-3)(4)=8\\\\2-3x-12=8\\\\-3x+(2-12)=8\\\\-3x-10=8\qquad|\text{add 10 to both sides}\\\\-3x=18\qquad|\text{divide both sides by (-3)}\\\\\boxed{x=-6}}\to\boxed{a.}
