165 - 9 = 156 / 2 = 78.

Do you understand? @scoutuj

So the total age minus the 9 yeras and then divide it by 2
OpenStudy (anonymous):
78

No wait, that's Priscilla's age, Add 78 + 9 and that's your answer.

Jack is 10 years older than Priscilla. Together their ages totaled 170 years. whats Jacks age?
So how would i figure it out
OpenStudy (conqueror):
Subtract total age by the total amount of years older Jack is, then divide the result by 2 and that's your answer.
OpenStudy (conqueror):
No wait, add the second result with the total amount of years.

170 - 10 = 160 / 2 = Priscilla's age + 10 = Jack's age.
There, a lot less confusing.
