Question 20535
Hello There:

I interpret your equation as:

(-12*m)/(-3) = -12

This can be written differently.

(-12/-3)*m = -12

Dividing negative 12 by negative 3 gives positive 4.

4*m = -12

Solve for m by multiplying each side by 1/4 (this is the same thing as dividing both sides by 4).

m = -3
