<PRE><B>Question 761069</B>
-6x = y
2x + y = -2

-6x - y = 0
 2x + y = -2
Add together
 -4x   = -2
   x   = -2/-4
   x   = 1/2
Substitute x = 1/2 in
2x + y = -2
2(1/2) + y = -2
   1   + y = -2
         y = -2 -1
         y = -3
  x= 1/2 y = -3

x - y = 1
y = 3x + 3

  x - y = 1
-3x + y = 3
Add
 -2x    = 4
   x    = 4/-2
   x    = -2
Substitute x = -2 in
x - y = 1
-2 - y = 1
   -y  = 1 + 2
    -y = 3
     y = -3
x = -2 y = -3
Hope this helps.
