To expand the expression $-3(2x - y)$ using the distributive property, follow these steps:

The distributive property states that $a(b + c) = ab + ac$. Applying this to $-3(2x - y)$:

$-3(2x - y) = -3 \cdot 2x + (-3) \cdot (-y)$

Now, calculate each term:

1. $-3 \cdot 2x = -6x$
2. $-3 \cdot (-y) = 3y$ (remember that a negative times a negative is a positive)

So, the expanded expression is:

$-6x + 3y$
