At a sporting event, the price for 3 cheeseburgers and 2 cups of lemonade is $14 and the price for 2 cheeseburgers and 4 cups of lemonade is $12. how much does it cost for 1 cheeseburger and 2 cups of lemonade?

C= the price of a cheeseburger and l = the price of a lemonade:



Divide the second equation by -2 to begin the process of solving by elimination:



Now that we have c, 4, we can plug it in to one of the equations to find l:



So, each cheeseburger is $4 and each lemonade is $1.  The final answer is:

1 cheeseburger and 2 cups of lemonade would cost $6.

1. 8 or -82. 14 or -143. -11, -3, 0, 7, 10
