x = -8, y = 10
If 4*y + 10 = 22Then 4*y = 12 (because 22 -10 = 12)Then y = 3 (because 4*3 =12)
If y + 3y + 10 = 70, then 4y + 10 = 70, and 4y = 60. We then find that y = 60/4 = 15.
2x+y = 10 x +y = 4 Subtract bottom equation from top equation: x = 6 Substitute the value of x into the equations to find the value of y: x = 6 and y = -2
x = 0 and y = 4
