3%28J%2BT%29=12%28J-T%29
%28J-3%29=2%28T-3%29
_________________
J-3=2T-6
J=2T-3
3%28J%2BT%29=12%28J-T%29
3J%2B3T=12J-12T%29
15T=9J
15T=9%282T-3%29
15T=18T-27%29
27=3T%29
9=T%29
J=2T-3
J=2%289%29-3
J=18-3
J=15
checking
3%28J%2BT%29=12%28J-T%29
3%2815%2B9%29=12%2815-9%29
3%2824%29=12%286%29
72=72
correct
