To determine the age of jiri:

Let P represent Pamela age

Let J represent Jiri age

p + j = 29 (their ages added together is 29)

p = j - 15 (Pam is 15 years younger (less) than Jiri)

We have a value for Pam, so plug it in:

j -15 + j = 29

2j - 15 = 29

Add 15 to both sides:

2j = 44

Divide by 2:

j = 22

Now find Pamela's age:

p = 22 - 15

p = 7

check:

7 + 22 = 29

29 = 29

Therefore the age of Jiri is 22 years
