Answer 2

Hello.

In 10 years, his age will be

`\mathrm{z+10}`

The sum of his current age and 10 equals his age in 10 years.

2 years ago his age was

`\mathrm{z-2}`

The difference of his current age and 2 equals his age 2 years ago.

7 years ago his age was

`\mathrm{z-7}`

The difference of his current age and 7 equals his age 7 years ago.

Therefore, his age after 10 years will be
`\mathrm{z+10}`, his age 2 years ago was
`\mathrm{z-2}`, and his age 7 years ago was
`\mathrm{z-7}`

I hope it helps.

Have a nice day.
