Answer 1

$x + \frac{3}{7} + \frac{7}{8} = 2 \frac{3}{8}$

$x + \frac{73}{56} = 2 \frac{3}{8}$

$x + \frac{73}{56} = \frac{19}{8}$

$x = \frac{19}{8} - \frac{73}{56}$

$x = \frac{15}{14}$

Answer 2

$x+\frac{3}{7} +\frac{7}{8} =\frac{19}{8}\\x=\frac{12}{8} +\frac{3}{7}=\frac{3}{2} +\frac{3}{7}= \frac{21-6}{14}=\frac{15}{14}$

$\frac{15}{14} =1\frac{1}{14}$
