The problem given can be solve using one variable. so let x be the total vote x = x(5/8) + 5/9(x - x(5/8)) + 48 so solve for x x - x(5/8) - 5/9(x - x(5/8)) = 48 x - x(5/8) - x(5/9) + x(25/72) = 48 x(1/6) = 48 x = 48*6 x = 288 blue votes = 288(5/8) = 180 red votes = 5/9(288 - 180) = 60 students riverside = 288 + 25 = 313
