I 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?

it's a word problem... one kids buys 3 CD and 1DVD for $20, another kid buys 2CD's and 2DVDs for $22... how much are the CD's and DVDs

Oh.. 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
