$y = - \frac{17}{42}$

#### Explanation:

$- \frac{3}{7} + y = - \frac{5}{6}$

Keep the variable on left- hand- side and take the rest on right - hand - side of the equation. Apply rule of transposition.

$y = - \frac{5}{6} + \frac{3}{7}$

Making the denominators same

$y = \left(- \frac{5}{6}\right)$ x $\left(\frac{7}{7}\right) + \frac{3}{7}$ x $\left(\frac{6}{6}\right)$

$y = \frac{- 35 + 18}{42}$

$y = - \frac{17}{42}$
