Question

For them knowing i have dyslexia...they sure like to screw with my head...
"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?


3J + 15 = 3J - 1
3(J + 15) = J - 1
J + 15 = 3J - 1
J + 15 = 3(J - 1)
