Question 1204515
If ben is 5 years older than Tim four years ago, the ratio of the ages 7:6 find their present age

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.
