Hi!

We need to isolate r on one side.

Subtract 8w from both sides.

8w - 8w - 3r = 45 - 8w

-3r = 45 - 8w

Divide by -3 on both sides.

-3r/-3 = 45/-3 - 8w

r = -15 - 8w

^the answer

Hope this helps! :)

Hello!

First, let's subtract 8w from both sides.

-3r=45-8w

Now, we divide both sides by -3.

r= -15-8w

I hope this helps!
