Simplifying F(-1x) = 7x + 9 Remove parenthesis around (-1x) F * -1x = 7x + 9 Reorder the terms for easier multiplication: -1F * x = 7x + 9 Multiply F * x -1xF = 7x + 9 Reorder the terms: -1xF = 9 + 7x Solving -1xF = 9 + 7x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7x' to each side of the equation. -7x + -1xF = 9 + 7x + -7x Combine like terms: 7x + -7x = 0 -7x + -1xF = 9 + 0 -7x + -1xF = 9 Reorder the terms: -9 + -7x + -1xF = 9 + -9 Combine like terms: 9 + -9 = 0 -9 + -7x + -1xF = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(9 + 7x + xF) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(9 + 7x + xF)' equal to zero and attempt to solve: Simplifying 9 + 7x + xF = 0 Solving 9 + 7x + xF = 0 Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + 7x + -9 + xF = 0 + -9 Reorder the terms: 9 + -9 + 7x + xF = 0 + -9 Combine like terms: 9 + -9 = 0 0 + 7x + xF = 0 + -9 7x + xF = 0 + -9 Combine like terms: 0 + -9 = -9 7x + xF = -9 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
