Simplifying f(-1) * 2x + 7 = 4 Reorder the terms for easier multiplication: -1 * 2f * x + 7 = 4 Multiply -1 * 2 -2f * x + 7 = 4 Multiply f * x -2fx + 7 = 4 Reorder the terms: 7 + -2fx = 4 Solving 7 + -2fx = 4 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -2fx = 4 + -7 Combine like terms: 7 + -7 = 0 0 + -2fx = 4 + -7 -2fx = 4 + -7 Combine like terms: 4 + -7 = -3 -2fx = -3 Divide each side by '-2x'. f = 1.5x-1 Simplifying f = 1.5x-1
