Answer 2

Answer:

-47/9

Step-by-step explanation:

$x + ( \frac{ - 7}{9} ) = - 6$

$x = - 6 + \frac{ - 7}{9}$

$x = \frac{ - 6}{1} + \frac{7}{9}$

LCM of 1,9 = 9

$x = \frac{ - 6 \times 9}{1 \times 9} + \frac{7 \times 1}{9 \times 1}$

$x = \frac{ - 54 + 7}{9} = \frac{ - 47}{9}$

The Other integer is -47/9

$\frac{ - 47}{9} + ( - \frac{ 7}{9}) =$

$\frac{ - 47}{9} - \frac{7}{9} =$

$\frac{ - 47 - 7}{9} = \frac{ - 54}{9} = - 6$
