Question

How do you simplify `-9(y-7)`?

Answer 1

Use the distributive property to get `-9y +63` .

Explanation:

The distributive property means the you can change `a(b+c)` into `ab + bc`.

In your problem, that means you can multiple `-9y` by each `y` and `-7` and add them together.

`-9 * y = -9y` and `-9 * -7 = 63`

So, the simplified answer is `-9y + 63`
