Answer 1

Hey there!

`Answer:\boxed{-x+-1}`

`Explanation:`

`4(5-2x)-21+7x`

Let's start off by distributing.

`(4)(5)+(4)(-2x)+-21+7x\\20+-8x+-21+7x`

Now in our second/last step, we will combine like terms.

`20+-8x+-21+7x\\(-8x+7x)+(20+-21)\\-x+-1`

`\boxed{-x+-1}\text{ is your answer.}`

Hope this helps!
