How to solve:
Assign a variable, preferably to Martin's age but you can assign one to William instead.
Martin, M
If William is HALF of Martin in age, then this is M/2.
Maybe easier to recognize that if William is some age w, then Martin is age 2w.
The sum of their ages was given as 18, so .
Solve for w, and you have William's age. Use this to get Martin's age.
