Question

Pamela's age is two times jiri's age. the sum of their ages is 51. what is jiris age?

Answer 1

J=Jiris

P=2J

P+J-51

Use substitution to solve

2J + J = 51

3J = 51

J=17

Plug 17 into one of the equations

J=17, P + J = 51

P + 17 = 51

P= 34

So Pamela is 34 and Jiris is 17

Answer 2

Jiri is seventeen years old.
