Subproblem 2
Set the factor '(3 + -5b + -1a)' equal to zero and attempt to solve:

Simplifying
3 + -5b + -1a = 0

Reorder the terms:
3 + -1a + -5b = 0

Solving
3 + -1a + -5b = 0

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

Add '-3' to each side of the equation.
3 + -1a + -3 + -5b = 0 + -3

Reorder the terms:
3 + -3 + -1a + -5b = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1a + -5b = 0 + -3
-1a + -5b = 0 + -3

Combine like terms: 0 + -3 = -3
-1a + -5b = -3

Add '5b' to each side of the equation.
-1a + -5b + 5b = -3 + 5b

Combine like terms: -5b + 5b = 0
-1a + 0 = -3 + 5b
-1a = -3 + 5b

Divide each side by '-1'.
a = 3 + -5b

Simplifying
a = 3 + -5b
Solution
a = {3 + -5b}
