Question 732984: solve by any appropriate method. if it is not possible to obtain one solution, state the reason. write the solution in the form (x,y).
1 + x - y = y + 4
4(x-y) = 3 - x

You can put this solution on YOUR website! solve by any appropriate method. if it is not possible to obtain one solution, state the reason. write the solution in the form (x,y).
1 + x - y = y + 4
4(x-y) = 3 - x
-------
Rearrange:
2y - x = -3
4y -5x = -3
------
Modify:
4y - 2x = -6
4y - 5x = -3
-----
Subtract and solve for "x":
3x = -3
x = -1
-------------
Solve for "y":
2y -x = -3
2y + 1 = -3
y = -2
=====
Solution: (-1,-2)
