Question

Simplify. 3/4−4z+5/4z−1/2+1/2z Enter your answer in the box.

Answer 1

Combine like terms:
3/4-1/2=1/4
-4z+5/4z+1/2z=-2 1/4z
so your answer is -2 1/4z+1/4

Answer 2

Answer: Our simplified form is

`(1)/(2)-(9)/(4)z`

Explanation:

Since we have given that

`(3)/(4)-4z+(5)/(4)z-(1)/(2)+(1)/(2)z`

Gather the like terms:

`(3)/(4)-4z+(5)/(4)z-(1)/(2)+(1)/(2)z\\\\=(3)/(4)-(1)/(2)-4z+(5)/(4)z+(1)/(2)z\\\\=(6-4)/(4)+(-16z+5z+2z)/(4)\\\\=(2)/(4)-(9)/(4)z\\\\=(1)/(2)-(9)/(4)z`

Hence, our simplified form is

`(1)/(2)-(9)/(4)z`
