Subproblem 2
Set the factor '(6 + -2b + -1a)' equal to zero and attempt to solve:

Simplifying
6 + -2b + -1a = 0

Reorder the terms:
6 + -1a + -2b = 0

Solving
6 + -1a + -2b = 0

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

Add '-6' to each side of the equation.
6 + -1a + -6 + -2b = 0 + -6

Reorder the terms:
6 + -6 + -1a + -2b = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -1a + -2b = 0 + -6
-1a + -2b = 0 + -6

Combine like terms: 0 + -6 = -6
-1a + -2b = -6

Add '2b' to each side of the equation.
-1a + -2b + 2b = -6 + 2b

Combine like terms: -2b + 2b = 0
-1a + 0 = -6 + 2b
-1a = -6 + 2b

Divide each side by '-1'.
a = 6 + -2b

Simplifying
a = 6 + -2b
Solution
a = {6 + -2b}
