Question

Pamela’s age is two times Jiri’s age. The sum of their age is 15. What is Jiri’s age?

Answer 1

Jiri is 5 (5x2= 10) so Pamela is is 10

Answer 2

Answer: Jiri is 5, Pamela is 10

Explanation:

Pamela age: x

Jiri age: y

x = 2y

x + y = 15

plug in the x value

2y + y = 15

combine

3y = 15

y = 5

solve for x

x = 2(5)

x = 10

check your answer

10 + 5 = 15
