need some help for ome problems im not gona have time to study them and i dont know how to do it or get answers and i have a test tommorow.

1.Fund the sum (g+6/g-1)+(-7/g-1)

2.Find the difference (q+4/q-1)-(5/q-1)

3.Find the sum (3/h-6)+(4/h+1)

i need help on these im stuck

You gotta buy more ()s. They are having a sale at Kmart.
I'm going to guess you mean
(g+6)/(g-1)+(-7/(g-1))
{What you wrote is the same as(g-1+6/g)+(-1-7/g)}
You have a common denominator so
(g+6)/(g-1)+(-7/(g-1)) =
(g+6-7)/(g-1)) =
(g-1)/(g-1) =
1

2. is the same. Give it a try

3. 3/(h-6)+4/(h+1)
Not common so you have to make it so.
3(h+1)/((h-6)(h+1))+4(h-6)/((h-6)(h+1) =
(3(h+1)+4(h-6))/((h-6)(h+1)) =
(3h+3+4h-24)/((h-6)(h+1)) =
(7h-21)/((h-6)(h+1)) =
7(h-3)/((h-6)(h+1))
