Answer 1

$(x + 9 \frac{7}{8} ) - 7 \frac{5}{18} = 7 \frac{3}{4}$

$x + 9\frac{7}{8} = 7 \frac{3}{4} + 7 \frac{5}{18}$

$x + 9 \frac{7}{8} = 14 \frac{27 + 10}{36}$

$x + 9 \frac{7}{8} = 14 \frac{37}{36}$

$x = 14 \frac{37}{36} - 9 \frac{7}{8}$

$x = 5 \frac{37 - 31.5}{36}$

$x = 5 \frac{5.5}{36}$

$x = 5 \frac{11}{72}$
