a = 0
Subproblem 2
Set the factor '(-1 + b + a)' equal to zero and attempt to solve:

Simplifying
-1 + b + a = 0

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

Solving
-1 + a + b = 0

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

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

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

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

Combine like terms: 0 + 1 = 1
a + b = 1

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

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

Simplifying
a = 1 + -1b
Solution
a = {0, 1 + -1b}
