Question 401547
Let c be Mr. Connors' age NOW.

In 15 years:
Mr. Wilson will be 20 + c years old
Mr. Connors will be c + 5 years old

Equation:
  20 + c = 1.5 (c + 5)
  20 + c = 1.5c + 7.5
12.5 + c = 1.5 c
    12.5 = 0.5c
25 years = c

Mr. Connors is 25 years old NOW.
Mr. Wilson is 15 years older than Mr. Connors, so he is 15 + 25 years. 
Mr. Wilson is 40 years old NOW.
