Write an algebraic expression to answer each question do this on a sheet of paper

Korolek [52]

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.
