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 '(4 + F + 2x)' equal to zero and attempt to solve: Simplifying 4 + F + 2x = 0 Solving 4 + F + 2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + F + -4 + 2x = 0 + -4 Reorder the terms: 4 + -4 + F + 2x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + F + 2x = 0 + -4 F + 2x = 0 + -4 Combine like terms: 0 + -4 = -4 F + 2x = -4 Add '-1F' to each side of the equation. F + -1F + 2x = -4 + -1F Combine like terms: F + -1F = 0 0 + 2x = -4 + -1F 2x = -4 + -1F Divide each side by '2'. x = -2 + -0.5F Simplifying x = -2 + -0.5F

Solution

x = {0, -2 + -0.5F}
