Question

If 8 years are subtracted from the present age of Jessica and 3 is added to the remaining number, then Olivia’s age can be found. If Olivia is two years older than Daniel who is 7 years old, then what is Jessica’s present age?

Answer 1

Jessica is 14 years old.

Explanation:

Let
`o` equal Olivia's age, let
`j` equal Jessica's age, and let
`d` equal Daniel's age. With this lets write out what we know:

`d = 7`

`o = d + 2 = 7 + 2 = 9`

`o = j - 8 + 3 = j - 5`

`9 = j - 5`

`j = 9 + 5 = 14`
