Question 61696
Given    4x - y  = -7    --->(1)
             2x + 2y = 4    --->(2)
Divide equation(2) by 2, we get
x + y  =  2
x =  2 - y       --->(3)
Substitue the  equation(3) in equation(1), we get...
4(2-y) -y = -7
8 - 4y -y = -7
8 -5y = -7
-5y = - 7 - 8
-5y = -15
y = -15/ - 5
y = 3  --->(4)
Now substitue the value of y =3 in eqution(3), we get
x = 2 - 3 = -1
x =-1
Therefore we have the  x =-1 and y = 3
