Answer:
Pamela = 30
Jiri = 40
Step-by-step explanation:
Two equations needed:
J-10 = P
P+J = 70
Plug and solve:
(J-10) + J = 70
2J - 10 =70
2J = 80
J = 40
40 - 10 = P
P=30
Answer:
30
Step-by-step explanation:
Let Jiri's age be x
Let Pamela's age be (x - 10)
The sum of their ages becomes
x + (x - 10) = 70
x + x - 10 = 70
2x - 10 = 70
2x =70+10
2x = 80
x = 40
Therefore, it means that Jiri's age is 40
Pamela's age is 40-10= 30
