Simplifying F(-1x) = 4(-1x) + 9 Remove parenthesis around (-1x) F * -1x = 4(-1x) + 9 Reorder the terms for easier multiplication: -1F * x = 4(-1x) + 9 Multiply F * x -1xF = 4(-1x) + 9 Remove parenthesis around (-1x) -1xF = 4 * -1x + 9 Multiply 4 * -1 -1xF = -4x + 9 Reorder the terms: -1xF = 9 + -4x Solving -1xF = 9 + -4x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4x' to each side of the equation. 4x + -1xF = 9 + -4x + 4x Combine like terms: -4x + 4x = 0 4x + -1xF = 9 + 0 4x + -1xF = 9 Reorder the terms: -9 + 4x + -1xF = 9 + -9 Combine like terms: 9 + -9 = 0 -9 + 4x + -1xF = 0 The solution to this equation could not be determined.
