My last problem I'm going to ask help with for today at least.

I set it up as follows:

x+y =34000

7x+8y=2530

-------------

(-7)x+y =34000

7x+8y=2530

-7x-7y=-23800

7x+8y=2530

__________

0x+1y = -235470

That just doesn't seem right, a person being in the whole for way more than they invested.
