You need to have two ways the variables are related. Take a look at some of the coin problems, mixture problems, tickets sold problems, etc. Do a search in the box at the top right and I'm sure you will see how they are done.

For example, if you have 7 coins (dimes and quarters) which add up to $1.15, then

d+q = 7

10d+25q = 115
