Question

Simplify 3/4 - 4 z + 5/4 z - 1/2 + 1/2 z enter your answer in the box.

Answer 1

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

First, put the like terms together:

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

Find the LCM of the first three to turn them into one massive fraction:

-16/4z + 5/4z + 2/4z + 3/4 - 1/2

Do the same for the last 2 fractions:

-16/4z + 5/4z + 2/4z + 3/4 - 2/4

Simplify everything (keeping like terms in mind)

-9/4z + 1/4

And that's the answer :)
