We are given,
1. 
As the denominator of both fractions are same we add the numerator
We get,

2. 
As the denominator of both the fractions are same we subtract the value in the numerator we get,


3. 
We first simplify the first term of the equation,

Now as the denominator is not same we use cross multiplication to perform the operation

On further simplifying we get,

Hence the answers are
1. 1
2. 
3.
