Simplifying f(x) = 2x + 5x + 3 Multiply f * x fx = 2x + 5x + 3 Reorder the terms: fx = 3 + 2x + 5x Combine like terms: 2x + 5x = 7x fx = 3 + 7x Solving fx = 3 + 7x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = 3x-1 + 7 Simplifying f = 3x-1 + 7 Reorder the terms: f = 7 + 3x-1
