You can put this solution on YOUR website!

5x-y=-5+.................(1)
3x-5y=-3.................(2)
--------------------------------------------
5x-y=-5+.................(1).......solve for y

5x+%2B+5=+y..........substitute in (2) and solve (2) for x
3x-+5%285x+%2B+5%29=-3
3x+-25x+-+25+=-3
+-22x+=+-3%2B25
+-22x+=+22
+x+=+22%2F-22+

+x+=+-1


now find y
y+=+5x+%2B+5..........
y+=+5%28-1%29+%2B+5..........
y+=+-5%2B+5..........
y+=+0..........
check:

5%28-1%29-+0=+-5+.................(1)

-5+=+-5+

3%28-1%29-+5%280%29+=+-3 .................(2)
-3+=+-3
