Let 4 years ago, Tim's age be x years
Ben's age 4 years ago. would have been x+5 years
(x+5)/x = 7/6
cross multiply
7x = 6(x+5)
7x=6x+30
7x-6x = 30
x=30
x+5=35
Add 4 to the values
Tim is currently 34 years old, and Ben is 39 years old.

If ben is 5 years older than Tim four years ago, the ratio of the ages 7:6 find their present age
Let Tim's age be T
Then Ben's is T + 5
Four years ago, Ben was and always will be 5 years older that Tim
Four years ago, Tim and Ben were T - 4, and T + 5 - 4, or T + 1, respectively
We then get:
7(T - 4) = 6(T + 1) ----- Cross-multiplying
7T - 28 = 6T + 6
7T - 6T = 6 + 28
Tim's age, or T = 34
Add 5 to Tim's age to get Ben's.
