Hey there!
The correct answer to this question is:
"A system is a set of equations that have the same variable."
If you've ever seen a system, they look a lot like this:
x + y = 12
x - y = 13
As you can see, they both have the same variables, x, and y. They are a set of equations with different methods of solving, and generate an answer in the form of coordinates.
Hope this helps!
