Answer 2

The given question is

$...... + \frac{3}{7} = - 1$

we have to find the blank.

let x be the value that we have to find.

$x + \frac{3}{7} = - 1$

on further calculations we get the value of x as

$7x + 3 = - 7 \\ 7x + 3 + 7 = 0 \\ 7x + 10 = 0 \\ 7x = - 10 \\ x = \frac{ - 10}{7}$

$\frac{ - 10}{7} + \frac{3}{7} = \frac{ - 10 + 3}{7} = \frac{ - 7}{ - 7} = - 1$

There the value in the blank is

$\frac{ - 10}{7}$
