Solve the equation $3.65 x - 2.31 y = 9.21$ for $y$ .
A) $y = \frac { 9.21 - 3.65 x } { 2.31 }$ or $y = 3.99 - 1.58 x$

B) $y = \frac { 9.21 + 3.65 x } { 2.31 }$ or $y = 3.99 + 1.58 x$

C) $y = \frac { 3.65 x - 9.21 } { 2.31 }$ or $y = 1.58 x - 3.99$

D) None of the above.

To isolate $y$ on one side of the equation, we need to get rid of the term that is multiplied by $y$. First, we can subtract $3.65x$ from both sides to get: 
$$-2.31y = -3.65x + 9.21$$ 
Next, we can divide both sides by $-2.31$ to get:
$$y = \frac{-3.65x + 9.21}{-2.31} = \frac{3.65x - 9.21}{2.31} = 1.58x - 3.99 $$
Therefore, the answer is (C).
