Simplifying f(x) = 6x + -2 Multiply f * x fx = 6x + -2 Reorder the terms: fx = -2 + 6x Solving fx = -2 + 6x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = -2x-1 + 6 Simplifying f = -2x-1 + 6 Reorder the terms: f = 6 + -2x-1
