Mrs,Perez is 3 times as old as her son, Jaypee. In 12 years, Mrs. Perez will be twice as old as Kaylee. What is the present age. Thank you.
----------------------------------------------------------------
Let P = Mrs. Perez' present age,
J = Jaypee --- " -----.
Then you have two equations
P = 3J,
P + 12 = 2(J+12).
Substitute (1) into (2). You will get
3J + 12 = 2(J+12 ---> 3J + 12 = 2J + 24 ---> 3J - 2J = 24 - 12 ---> J = 12.
Answer. J = 12, P = 36.
