No.
7x + 5y 7(3) + 5(2) 21 + 10 = 31
80 = 3y + 2y + 4 + 1 80 = 5y + 5 80 - 5 = 5y + 5 - 5 75 = 5y 75 / 5 = 5y / 5 15 = y
5y-4 = 7 5y = 7+4 = 11 y = 11 / 5 = 2.2
8 + 5y = 18 Therefore, 5y = 10 y = 10/5 y = 2
5y + x = 0 subtract 5y from each side, then x = -5y
If y equals 3, 7 - 5y would be:7 - 5(3)Simplify.7 - 15 = -8.In conclusion, 7 - 5y = -8.
