Question

"I am 3 times as old as Sue is," Frank said to Ann. "On the other hand, I am 15 years older than John while Sue is 1 year younger than John. How old am I?"

If J represents John's age, then which of the following equations could be used to solve the problem?

Answer 1

Answer:

24

Step-by-step explanation:

F = 3S

F = J + 15

S = J - 1

J + 15 = 3 (J -1)

2J = 18

J = 9

Age of Frank, F = 9 + 15 = 24
