The answer is C. Just took the quiz and B was wrong. It needs to be the one with the smaller 12.
I think it’s the first option
Well first you have to add common like terms in this case 2r and -6r to get -4r now your equation is -4r+8=40, now subtract 8 from both sides to leave r by itself and get -4r=32, now divide both sides by -4 to get r=-8
