Answer 1

To find the value of x, we can combine the like terms on the left side of the equation:

-3x + 7x = 4x

So the equation becomes:

4x = -12

To solve for x, we divide both sides of the equation by 4:

(4x)/4 = (-12)/4

x = -3

Therefore, the value of x is -3.

So the correct answer is A) -3.
