Mark is 15 years younger than Ashley. The sum of their ages is 55. Write a set of equations to determine Mark (M) age and Ashley (A) age.

I need to write this as a set of equations (2 equations) with 2 variables (M and A), but it only gives me the numbers 55 and 15 and I don't know how to write it.
Please help!
