To solve for x, we need to simplify the equation by combining like terms:

First, we combine the 2x and -4x terms:

2x - 4x = -2x

So the equation becomes:

-2x - 3 = -27

Next, we want to eliminate the -3 term on the left side of the equation by adding 3 to both sides:

-2x - 3 + 3 = -27 + 3
-2x = -24

To solve for x, we divide both sides of the equation by -2:

-2x/-2 = -24/-2
x = 12

Therefore, the solution is (b) x = 12.
