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

Simplifying
-5b + -1a = 0

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

Solving
-1a + -5b = 0

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

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

Combine like terms: -5b + 5b = 0
-1a + 0 = 0 + 5b
-1a = 0 + 5b
Remove the zero:
-1a = 5b

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

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

Simplifying
b + -1a = 0

Reorder the terms:
-1a + b = 0

Solving
-1a + b = 0

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

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

Combine like terms: b + -1b = 0
-1a + 0 = 0 + -1b
-1a = 0 + -1b
Remove the zero:
-1a = -1b

Divide each side by '-1'.
a = b

Simplifying
a = b
Solution
a = {-5b, b}
