Jackson’s age was 2/fifth of the age he will be 20 years from now seven years ago. How old is Jackson now?

Margaret [11]

Let's say Jackson's age now is x.

In 20 years, (so 20+x), Jackson seven years ago will be 2/5ths of that age.

So 2/5(20+x)=x-7

Then you solve the equation
8+2/5x=x-7
15=3/5x
x=25
Jackson is 25 years old.

Let's check our answer! In 20 years, Jackson will be 45. 7 years ago, he was 18. 2/5 of 45 is 18. Our answer is correct!
