Subproblem 2
Set the factor '(7b + -12a + 3ab)' equal to zero and attempt to solve:

Simplifying
7b + -12a + 3ab = 0

Reorder the terms:
-12a + 3ab + 7b = 0

Solving
-12a + 3ab + 7b = 0

Move all terms containing a to the left, all other terms to the right.

Add '-7b' to each side of the equation.
-12a + 3ab + 7b + -7b = 0 + -7b

Combine like terms: 7b + -7b = 0
-12a + 3ab + 0 = 0 + -7b
-12a + 3ab = 0 + -7b
Remove the zero:
-12a + 3ab = -7b
