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
Ok, thank you!
how silly of me 5x16 is 80, not 90
the correct answer is -95
