Answer 2

Answer:

$x = \frac{13}{56}$

Step-by-step explanation:

Let the number be x

$x + (\frac{ - 3}{8} ) = - \frac{ 1}{7} \\ \\ = > x - \frac{ 3}{8} = - \frac{ 1}{7} \\ \\ = > x = \frac{3}{8} - \frac{1}{7} \\ \\ = > x = \frac{(7 \times 3) - (8 \times 1)}{8 \times 7} \\ \\ = > x = \frac{21 - 8}{56} \\ \\ = > x = \frac{13}{56}$

HOPE IT HELPS YOU.
