The correct answer is C. x = 9.
To find this first distribute the numbers on the outside of the parenthesis.
-4(6x + 3) = -12(x + 10)
-24x - 12 = -12x - 120
Now move all the constant values to the right and all of the x values to the left.
-24x - 12 = -12x - 120
-24x = -12x - 108
-12x = -108
Now divide by -12 to solve
x = 9
