Answer:
(6)/(7)

Explanation:

$(5)/(7)-\left(-(1)/(7)\right)$

Once you take off the parenthesis, your sign should change from negative to positive.

$(5)/(7)-\left(-(1)/(7)\right)=(5)/(7)+(1)/(7)\\\\(5)/(7)+(1)/(7)$

The fractions now both have the same denominator. Thus, we can add the numerators.

$(5+1)/(7)\\\\5+1\\\\6=(6)/(7)$

Therefore,
$(5)/(7)-\left(-(1)/(7)\right)=(6)/(7)$
