To get our solution, first simplify the equation:

- (1)/(6) +(- (3)/(7) )
=>
- (1)/(6) - (3)/(7)
Now, find a common denominator, which would be 42.

- (7)/(42) - (18)/(42)
Since we now have a common denominator, we can straight up add the numerators:

- (25)/(42)

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

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.
