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

Simplifying
n = 0

Solving
n = 0

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

Simplifying
n = 0
Subproblem 2
Set the factor '(3 + A)' equal to zero and attempt to solve:

Simplifying
3 + A = 0

Solving
3 + A = 0

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

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

Combine like terms: 3 + -3 = 0
0 + A = 0 + -3
A = 0 + -3

Combine like terms: 0 + -3 = -3
A = -3

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

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

Simplifying
0 = -3 + -1A
