Question

How do you simplify `-y + 9z -16y - 25z`?

Answer 1

`-17y - 16z`

Explanation:

To simplify this, we have to combine like terms. First, let's color code the like terms:
`color(red)(-quady) quadcolor(blue)(+quad9z) quadcolor(red)(-quad16y) quadcolor(blue)(-quad25z)`

Now combine like terms:
`-17y - 16z`
