It would help if you proofread your questions before you posted them.

How can father's age be "five years as old as his son"? Is "he" and "him" father or son?
Answered by oobleck

In that case, you have
in ten years, the sum will be x+10 + 5x+10

as for what "these age is now 17" means, I have no clue.
