Answer:

-2 1/4z +1/4

Step-by-step explanation:

3/4 - 4z +5/4 z- 1/2 + 1/2 z

Put like terms near each other

3/4- 1/2  - 4z +5/4 z+ 1/2 z

We need to get common denominators to combine

First the constant terms

3/4 - 1/2*2/2  

3/4 - 2/4 = 1/4

Then the variable terms

-4z *4/4 +5/4z + 1/2z *2/2

-16z/4 + 5/4z +2/4z

-9/4z

Changing from an improper fraction to a mixed number

-2 1/4 z

-2 1/4z +1/4
