Multiple Choice

Solve the equation for the specified variable.
- $-3 k+a r=r-2 y$ for $r$

A) $r=\frac{3 k-2 y}{a-1}$ or $r=\frac{-3 k+2 y}{1-a}$

B) $r=\frac{-3 k+2 y}{a-1}$ or $r=\frac{3 k-2 y}{1-a}$

C) $r=\frac{a-1}{3 k-2 y}$ or $r=\frac{1-a}{-3 k+2 y}$

D) $r=\frac{-3 k+a}{1-2 y}$ or $r=\frac{3 k-a}{2 y-1}$
