4t/5 + 3s/7 - t/3 - s/2 = (4t/5 - t/3) - 3s/7 - s/2
                                 = 12t/15 - 5t/15 - 6s/14 - 7s/14
                                 = 7t/15 - 13s/14
                                 = -13s/14 + 7t/15

4/5 t + 3/7 s - 1/3 t - 1/2 s

=>> 4/5 t - 1/3 t + 3/7 s - 1/2 s
=>> 12/15 t - 5/15 t + 6/14 - 7/14 s
=>> 7/15 t + - 1 / 14 s
