Solve for x:

(3 x) / 4 = - 12

Multiply both sides of (3 x) / 4 = - 12 by 4/3:

(4*3 x) / (3*4) = - 12*4/3

4/3*3/4 = (4*3) / (3*4):

(4*3) / (3*4) x = - 12*4/3

4/3 (-12) = (4 (-12)) / 3:

(4*3 x) / (3*4) = (-12*4) / 3

(4*3 x) / (3*4) = (3*4) / (3*4) * x = x:

x = (-12*4) / 3

(-12) / 3 = (3 (-4)) / 3 = - 4:

x = 4*-4

4 (-4) = - 16:

Answer: x = - 16
