Best ResponseYou've already chosen the best response.0I am not sure you have everything here that is needed. If it says solve for x then you will have 2x + 2y = 22 2x = 22  2y x = 11  y Are you sure this is what you want?

Best ResponseYou've already chosen the best response.0Oh.. c = CD's d = DVD's 3c + d = 20 2c + 2d = 22 6c  2d = 40 Multiplied by 2 2c + 2d = 22 4c = 18 added them up. c = 4.5 Substitute back in. 3c + d = 20 3(4.5) + d = 20 13.5 + d = 20 d = 6.5 CD's = $4.50 DVD's = $6.50
