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!
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! :)
