Subproblem 1
Set the factor 'b' equal to zero and attempt to solve:

Simplifying
b = 0

Solving
b = 0

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

Simplifying
b = 0
Subproblem 2
Set the factor '(-4 + g)' equal to zero and attempt to solve:

Simplifying
-4 + g = 0

Solving
-4 + g = 0

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

Add '4' to each side of the equation.
-4 + 4 + g = 0 + 4

Combine like terms: -4 + 4 = 0
0 + g = 0 + 4
g = 0 + 4

Combine like terms: 0 + 4 = 4
g = 4

Add '-1g' to each side of the equation.
g + -1g = 4 + -1g

Combine like terms: g + -1g = 0
0 = 4 + -1g

Simplifying
0 = 4 + -1g
