If 3 - x = 2x - 3, then 4x =

(A) - 24
(B) -8
(C) 0
(D) 8
(E) 24

Adding 3 and X to both sides we have 3 + 3 = 2x + x

6 = 3x leading to x = 2

if x = 2 then 4x = 4 x 2 = 8.

The answer is D.

3 - x = 2x - 3, then 4x =

step 1: add 3 to both sides --> 3 - x + 3 = 2x - 3 + 3 --> 6 - x = 2x
step 2: add x to both sides --> 6 - x + x = 2x + x --> 6 = 3x
step 3: divide both sides by 3 --> 6/3 = 3x/3 --> 2 = x
step 4: multiply both sides by 4 --> 2*4 = x*4 --> 8 = 4x

The correct answer is therefore D.
