Question

Pamela is 13 years older than Jiri. The sum of their ages is 73 . What is Jiri's age?

Answer 1

73-13=60
60/2=30
30 is jiri age

Answer 2

43 is pamela

Answer 3

(13+J)+J=73
2J = 73 -13
J = 60/2
J=30
Jiri = 30

Pamela is = 30+13=43

Answer 4

let the age of pamela = P
and the age of jiri = J
P = 13 + J
P + J = 73
then substitute the value of P
( 13 + j )+J = 73
13 + 2J = 73
2J = 60
J = 30
thus jiri's age is 30
