Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(-120 + P + x)' equal to zero and attempt to solve: Simplifying -120 + P + x = 0 Solving -120 + P + x = 0 Move all terms containing x to the left, all other terms to the right. Add '120' to each side of the equation. -120 + P + 120 + x = 0 + 120 Reorder the terms: -120 + 120 + P + x = 0 + 120 Combine like terms: -120 + 120 = 0 0 + P + x = 0 + 120 P + x = 0 + 120 Combine like terms: 0 + 120 = 120 P + x = 120 Add '-1P' to each side of the equation. P + -1P + x = 120 + -1P Combine like terms: P + -1P = 0 0 + x = 120 + -1P x = 120 + -1P Simplifying x = 120 + -1P

Solution

x = {0, 120 + -1P}
