Answer 1

you will teach 22 years and 3 months

Answer 2

Answer: 21 years and 9 months

Step-by-step explanation:

Since,

          I started teaching at the age of 21 years and left at the age of 43 years

=> (43 - 21)years = 22 years

Then,

         for month, we have:

=> (2 - 5)months = (-3) months

Now,

         22 years and (-3) months = 12 -3

                                                      = 9

and,

      (22 - 1)years = 21 years

Hence, I have been teaching ​for 21 years and 9 months.
