omgz i did this today!!
X+Y=11 (equation 1)
2X+8Y=52 (equation 2)
X+Y=11 (x 2)
2X+2Y=22 (equation 3)
2X+2Y=22 (
2X+8Y = 52
(equation 2 - equation 3)
2X+8Y = 52 - 2X+2Y=22
6Y = 30 (divide by 6)
Y = 5
sorry had to use my book took awhile
and too find X u have to do what y is in the formula so
X+Y=11
(-5)
X = 6
so vicky is wrong as x = 6 and y = 5
