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 '(-3 + F + -9x)' equal to zero and attempt to solve: Simplifying -3 + F + -9x = 0 Solving -3 + F + -9x = 0 Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + F + 3 + -9x = 0 + 3 Reorder the terms: -3 + 3 + F + -9x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + F + -9x = 0 + 3 F + -9x = 0 + 3 Combine like terms: 0 + 3 = 3 F + -9x = 3 Add '-1F' to each side of the equation. F + -1F + -9x = 3 + -1F Combine like terms: F + -1F = 0 0 + -9x = 3 + -1F -9x = 3 + -1F Divide each side by '-9'. x = -0.3333333333 + 0.1111111111F Simplifying x = -0.3333333333 + 0.1111111111F

Solution

x = {0, -0.3333333333 + 0.1111111111F}
