Simplifying f(-1x) = x + 6(-1x) + 3 Remove parenthesis around (-1x) f * -1x = x + 6(-1x) + 3 Reorder the terms for easier multiplication: -1f * x = x + 6(-1x) + 3 Multiply f * x -1fx = x + 6(-1x) + 3 Remove parenthesis around (-1x) -1fx = x + 6 * -1x + 3 Multiply 6 * -1 -1fx = x + -6x + 3 Reorder the terms: -1fx = 3 + x + -6x Combine like terms: x + -6x = -5x -1fx = 3 + -5x Solving -1fx = 3 + -5x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by '-1x'. f = -3x-1 + 5 Simplifying f = -3x-1 + 5 Reorder the terms: f = 5 + -3x-1
