Simplifying f(x) = x * 2 + -6x + 15f(-3) Multiply f * x fx = x * 2 + -6x + 15f(-3) Reorder the terms for easier multiplication: fx = 2x + -6x + 15f(-3) Reorder the terms for easier multiplication: fx = 2x + -6x + 15 * -3f Multiply 15 * -3 fx = 2x + -6x + -45f Reorder the terms: fx = -45f + 2x + -6x Combine like terms: 2x + -6x = -4x fx = -45f + -4x Solving fx = -45f + -4x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '45f' to each side of the equation. 45f + fx = -45f + 45f + -4x Combine like terms: -45f + 45f = 0 45f + fx = 0 + -4x 45f + fx = -4x Combine like terms: -4x + 4x = 0 45f + fx + 4x = 0 The solution to this equation could not be determined.
