A computer store manager buys several computers of the same model for $7,600. The store can regain this investment by selling all but 9 of the computers at a profit of $360 per computer. To do this, how many computers must be sold, and at what price?

xy= 7,600

(x-9)(y+360)= 7600

360x-9y-7600-3240= 7600

360x-9y= 3240

x= 7600/y

360(7600/y)=9y+3240

That doesn't help me answer the questions though! How many computers sold and at what price!
