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 '(-40 + P + 0.25x)' equal to zero and attempt to solve: Simplifying -40 + P + 0.25x = 0 Solving -40 + P + 0.25x = 0 Move all terms containing x to the left, all other terms to the right. Add '40' to each side of the equation. -40 + P + 40 + 0.25x = 0 + 40 Reorder the terms: -40 + 40 + P + 0.25x = 0 + 40 Combine like terms: -40 + 40 = 0 0 + P + 0.25x = 0 + 40 P + 0.25x = 0 + 40 Combine like terms: 0 + 40 = 40 P + 0.25x = 40 Add '-1P' to each side of the equation. P + -1P + 0.25x = 40 + -1P Combine like terms: P + -1P = 0 0 + 0.25x = 40 + -1P 0.25x = 40 + -1P Divide each side by '0.25'. x = 160 + -4P Simplifying x = 160 + -4P

Solution

x = {0, 160 + -4P}
