Jacqueline was 24 when her son was born. Now she is 3 times her son's age. How old is Jaqueline now?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let J = Jaqueline age now.
We are given that Jaqueline is 24 years older than her son,
whose age is, consequently, J- 24.
And we are given that
J = 3*(J-24).
This is yours equation. Solve it for J:
J = 3J - 72 ---> J - 3J = -72 ---> -2J = -72 ---> J = = 36.
Answer. Jaqueline is 36 years old now.
