r/5-3=2r/5+16

Please help me solve for r, I just can not seem to figure it out.

I would multiply each term by 5 to get

r - 15 = 2r + 90

Now you have a very simple equation.

Can you take it from there?

I think so...I got r=105

Watch your sign.

Should have been r = -105

the correct answer is -95
