Simplifying 4x + 8y = 30.60 Solving 4x + 8y = 30.60 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8y' to each side of the equation. 4x + 8y + - 8y = 30.60 + - 8y Combine like terms: 8y + - 8y = 0 4x + 0 = 30.60 + - 8y 4x = 30.60 + - 8y Divide each side by '4'. x = 7.65 + - 2y Simplifying x = 7.65 + - 2y
