Answer 2

Answer:

s=36/5

t=36/5

Step-by-step explanation:

$s - t = 0 \: \: \: \: \: \: \: \: \: (1)$

$\frac{s}{3} + \frac{t}{2} = 6 \: \: \: \: \: \: (2)$

$from \: (1)$

$s = t$

$putting \: this \: value \: in \: (2)$

$\frac{t}{3} + \frac{t}{2} = 6$

$\frac{2t + 3t}{6} = 6$

$5t = 6 \times 6$

$t = \frac{36}{5}$

$putting \: this \: value \: in \: (1)$

$s - \frac{36}{5} = 0$

$s = \frac{36}{5}$
