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 '(20 + F + -5x2)' equal to zero and attempt to solve: Simplifying 20 + F + -5x2 = 0 Solving 20 + F + -5x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + F + -20 + -5x2 = 0 + -20 Reorder the terms: 20 + -20 + F + -5x2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + F + -5x2 = 0 + -20 F + -5x2 = 0 + -20 Combine like terms: 0 + -20 = -20 F + -5x2 = -20 Add '-1F' to each side of the equation. F + -1F + -5x2 = -20 + -1F Combine like terms: F + -1F = 0 0 + -5x2 = -20 + -1F -5x2 = -20 + -1F Divide each side by '-5'. x2 = 4 + 0.2F Simplifying x2 = 4 + 0.2F The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
