Tara was out selling girl scout cookies. She noticed that the caramel cookies were the most popular, with lemon cookies being the next most favored. She actually sold three boxes lemons cookies for every four boxes of caramel cookies. If she sold 63 boxes of caramel cookies altogther, how many boxes of cameral cookies were sold? Thank you for your help.

L=3(C/4)
L+C=63
Can you handle it from here?
