A=2J/3
IN 12 YEARS A WILL BE A+12
IN 12 YEARS J WILL BE J+12
USING THE (2J/3) FOR A's GURRENT AGE WE ADD 12 YEARS OR 2J/3+12
USING J+12 FOR J's AGR 12 YEARS FROM NOW.
ADDING THESE 2 AGES WE GET:
2J/3+12+J+12=54
2J/3+J=54-12-12
5J/3=54-24
5J/3=30
5J=3*30
5J=90
J=90/5
J=18 IS THE CURRENT AGE OF J.
A=2*18/3=36/3=12 IS THE CURRENT AGE OF A.
PROOF
18+12+12+12=54
54=54
