-2X+3Y=4
5X+4Y=13
--------------------
Multiply thru the 1st equation by 5
Multiply thru the 2nd equation by 2
-------
-10x + 15y = 20
10x + 8y = 26
-------------------
Add and solve for "y":
23y = 46
y = 2
-----
Solve for "x":
-2x + 3y = 4
-2x + 3*2 = 4
-2x = -2
x = 1
-------
Solution:: (1,2)
===================
Cheers,
