Question

Find what r equals -8 - 6(r + 4) = -8r - 38
(Explanation please)

Answer 1

`r=-3`

Explanation:

Alright.

`-8-6(r+4)=-8r-38`

First, we'll distribute that
`-6`.

`-8-6r-24=-8r-38`

Next, I'm going to move the
`-8r` to the other side.

`-8-6r-24+8r=-38`

That means the sign changes. Now, I'll combine like terms on the left.

`2r-32=-38`

Now, I'll move the
`-32` over to the right.

`2r=-6`

Divide both sides by 2.

`r=-3`

And we're done!

Answer 2

r = -3

Explanation:

-8-6(r+4)=-8r-38 distribute -6 into the parentheses

-8-6r-24=-8r-38 simplify

-6r-32=-8r-38 add 8r to both sides

2r-32=-38 add 32 to both sides

2r=-6 divide both sides by 2

r = -3
