Question 462921
Solve for x and y: 
8x+5y=5
7x+10y=-1
----
Multiply thru the 1st equation:
16x + 10y = 10
7x  + 10y = -1
------------------
Subtract and solve for "x":
9x = 11
x = 11/9
-----------------
Solve for "y":
3x + 5y = 5
3(11/9) + 5y = (45/9)
-------
5y = 12/9
y = 12/45
---
y = 4/15
-------------
