Okay. The answer to this question will be negative. If you want to work it on paper, find the LCD of 6 and 7, which is 42. -7/42 - 18/42 is -25/42. The sum is -25/42.
To get our solution, first simplify the equation:
[tex]- \frac{1}{6} +(- \frac{3}{7} )[/tex]
=>[tex]- \frac{1}{6} - \frac{3}{7} [/tex]
Now, find a common denominator, which would be 42.
[tex]- \frac{7}{42} - \frac{18}{42} [/tex]
Since we now have a common denominator, we can straight up add the numerators:
[tex]- \frac{25}{42} [/tex]

The answer to this problem would be -25/42. Hope this helps and have a great day!
