You can put this solution on YOUR website!
(1) +8x+%2B+7y+=+0+
(2) -9x+%2B+2y+=+0+
---------------
(1) y+=+%28-8%2F7%29%2Ax
(2) y+=+%289%2F2%29%2Ax
---------------
These are straight lines that meet at the origin.
The solution is x+=+0 and y+=+0
Here's a plot:
+graph%28+400%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+%28-8%2F7%29%2Ax%2C+%289%2F2%29%2Ax%29+
