Question

How do you write the expression for: Nine times the difference of y and z, increased by 3z?

Answer 1

`(9*(y - z)) + 3z`

Explanation:

"the difference of y and z" can be written as `y - z`.

"Nine times" this difference can be written as: `9*(y - z)`

and if you "increase this term by `3z`" you will have:

`(9*(y - z)) + 3z`
