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 '(5 + F + -2x3)' equal to zero and attempt to solve: Simplifying 5 + F + -2x3 = 0 Solving 5 + F + -2x3 = 0 Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + F + -5 + -2x3 = 0 + -5 Reorder the terms: 5 + -5 + F + -2x3 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + F + -2x3 = 0 + -5 F + -2x3 = 0 + -5 Combine like terms: 0 + -5 = -5 F + -2x3 = -5 Add '-1F' to each side of the equation. F + -1F + -2x3 = -5 + -1F Combine like terms: F + -1F = 0 0 + -2x3 = -5 + -1F -2x3 = -5 + -1F Divide each side by '-2'. x3 = 2.5 + 0.5F Simplifying x3 = 2.5 + 0.5F The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
