Answer: Choice C) -2b - 1</h3>
=================================================
Work Shown:
3r + 2 - r = -4b
(3r-r) + 2 = -4b
2r + 2 = -4b
2r+2-2 = -4b-2 .... subtracting 2 from both sides
2r = -4b-2
2r/2 = (-4b-2)/2 .... dividing both sides by 2
r = (-4b-2)/2
r = (-4b)/2 - 2/2 ... break up the fraction
r = -2b - 1
