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

Simplifying
-1 + 3b = 0

Solving
-1 + 3b = 0

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

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

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

Combine like terms: 0 + 1 = 1
3b = 1

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

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

Simplifying
0 = 1 + -3b
