Question 847339: I have to find the value of X and Y and I am looking for the sides of 2X+y=10 and the other side of 2X-Y=6. One side say just says 2X-Y and the congruent side of this is 6. The other side just says 2X+Y and the congruent side to this one is 10. I am confused on how to solve this. I would really like it if you could explain how to solve this equation and what you did step by step please.

-----
2x+y = 10
2x-y = 6
------------
Add and solve for "x":
4x = 16
x = 4
-----
Solve for "y":
2x+y = 10
2*4 + y = 10
y = 2
