Question

How do you solve `-6(3n-3)=-90` using the distributive property?

Answer 1

`color(blue)(n = 4`

Explanation:

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

`-6(3n-3) = -90`

`(-6 * 3n ) + (-6 * -3) = -90, " using distributive property"`

`-18n + 18 = - 90`

`-18n = -90 + 18 = -72`

`color(blue)(n =cancel (-72)^color(red)(4) / cancel(-18) = 4`
