Subproblem 2
Set the factor '(-20 + n)' equal to zero and attempt to solve:

Simplifying
-20 + n = 0

Solving
-20 + n = 0

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

Add '20' to each side of the equation.
-20 + 20 + n = 0 + 20

Combine like terms: -20 + 20 = 0
0 + n = 0 + 20
n = 0 + 20
