Simplifying -5(4x + 4y) = -5(8) (4x * -5 + 4y * -5) = -5(8) (-20x + -20y) = -5(8) Multiply -5 * 8 -20x + -20y = -40 Solving -20x + -20y = -40 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '20y' to each side of the equation. -20x + -20y + 20y = -40 + 20y Combine like terms: -20y + 20y = 0 -20x + 0 = -40 + 20y -20x = -40 + 20y Divide each side by '-20'. x = 2 + -1y Simplifying x = 2 + -1y
