5(x + y)
5y - 4 + 9y - 1y + 15= 5y + 9y - 1y + 15 - 4= (5 + 9 - 1)y + (15 - 4)= 13y + 9
5y - 8 = 2 (3y + 5)Eliminate the parentheses so thatwe can see what's going on:5y - 8 = 6y + 10Subtract 5y from each side of the equation:-8 = y + 10Subtract 10 from each side:-18 = y
80 = 3y + 2y + 4 + 1 80 = 5y + 5 80 - 5 = 5y + 5 - 5 75 = 5y 75 / 5 = 5y / 5 15 = y
