Subproblem 2
Set the factor '(2 + -7b + -1a)' equal to zero and attempt to solve:

Simplifying
2 + -7b + -1a = 0

Reorder the terms:
2 + -1a + -7b = 0

Solving
2 + -1a + -7b = 0

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

Add '-2' to each side of the equation.
2 + -1a + -2 + -7b = 0 + -2

Reorder the terms:
2 + -2 + -1a + -7b = 0 + -2

Combine like terms: 2 + -2 = 0
0 + -1a + -7b = 0 + -2
-1a + -7b = 0 + -2

Combine like terms: 0 + -2 = -2
-1a + -7b = -2

Add '7b' to each side of the equation.
-1a + -7b + 7b = -2 + 7b

Combine like terms: -7b + 7b = 0
-1a + 0 = -2 + 7b
-1a = -2 + 7b

Divide each side by '-1'.
a = 2 + -7b

Simplifying
a = 2 + -7b
Solution
a = {2 + -7b}
