Answer:


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:

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
