Question 170288
First order of business, put all the x's and y's to one side:
2x - 2y =3+x
x = 3y + 4
.
Rearranging then, we have:
x - 2y =3
x - 3y =4
.
Now, using the "elimination method", subtract the second equation from the first:
 x - 2y =  3
-x + 3y = -4
---------------
      y = -1 
.
Now, use the above definition of 'y' and substitute it into equation 2:
x = 3y + 4
x = 3(-1) + 4
x = -3 + 4
x = 1
.
Solution:
(x,y) = (1, -1)
