Answer: y= -2; x = 8
Step-by-step explanation:
X=-4y.......equation 1
3x+2y=20......equation 2
Substitute the value of x into equation 2
3 (-4y) + 2y = 20
-12y + 2y = 20
-10y = 20
Divide both sides by -10
y = 20/-10
y = -2
Substitute the value of y into equation 1 to get the value of x
x = - 4(-2)
x = 8
