Explanation:

First, expand the bracket, the negative signs cancel (multiplying two negatives results in a positive)
-1/4(-3) = -1/4*-3−14(−3)=−14⋅−3
=>1/4*3= 3/4 ⇒14⋅3=34

Then simply add the numerators, since the denominators are the same:
3/4+5/4=8/434+54=84

By dividing the top and bottom by 4, this simplifies to 22
