I've been doing some math contest stuff, and I find a lot of questions that's like 3 different variables, with 2 equations. It asks me to find the number of different possible combinations.
Here's an example:
a+b+c = 110
a+2b+5c = 200
How many different combo of abc are there? (a, b, c are integers. and positive in this question, but not necessarily all questions.)
How do I solve these questions in general?
