Answer:  Choice C)  -2b - 1

=================================================

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

Answer:

[tex]-2b-1[/tex]

Step-by-step explanation:

[tex]3r+2-r=-4b[/tex]

[tex]2r+2=-4b[/tex] (Subtract r from 3r)

[tex]2r+2-2=-4b-2[/tex] (Subtract 2 from both sides)

[tex]\frac{2r}{2} = \frac{-2b-1}{2}[/tex] (Divide both sides by 2)

[tex]r=-2b-1[/tex]
