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
Hope this helps

2r( 1 - 3×8) = 40
2r (1 - 24) = 40
2r(-23)=40
-46r=40
r = -40/46
r. = - 0.86
