Subproblem 1

Set the factor '(50 + -1n)' equal to zero and attempt to solve: Simplifying 50 + -1n = 0 Solving 50 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '-50' to each side of the equation. 50 + -50 + -1n = 0 + -50 Combine like terms: 50 + -50 = 0 0 + -1n = 0 + -50 -1n = 0 + -50 Combine like terms: 0 + -50 = -50 -1n = -50 Divide each side by '-1'. n = 50 Simplifying n = 50

Subproblem 2

Set the factor '(54 + n)' equal to zero and attempt to solve: Simplifying 54 + n = 0 Solving 54 + n = 0 Move all terms containing n to the left, all other terms to the right. Add '-54' to each side of the equation. 54 + -54 + n = 0 + -54 Combine like terms: 54 + -54 = 0 0 + n = 0 + -54 n = 0 + -54 Combine like terms: 0 + -54 = -54 n = -54 Simplifying n = -54

Solution

n = {50, -54}
