I guess that's the answer 11x-y

Define their age
---------------------------------------------------------------------------------------
Let Jim be x years old
Jim = x
Father = x + 31 ← Jim is 31 years younger than the father
Grandfather = x + 70 ← Grandfather is 70 years older than Jim
---------------------------------------------------------------------------------------
Combined age is 137, find x
---------------------------------------------------------------------------------------
x + (x + 31) + (x + 70) = 137
x + x + 31 + x + 70 = 137
3x + 101 = 137
3x = 137 - 101
3x = 36
x = 12
---------------------------------------------------------------------------------------
Find their age
---------------------------------------------------------------------------------------
Jim = x = 12
Father = x + 31
Father = 12 + 31
Father = 43
Grandfather = x + 70
Grandfather = 12 + 70
Grandfather = 82
---------------------------------------------------------------------------------------
Answer: Jim = 12 ; Father = 43 ; Grandfather = 82
