Let's solve the equation $3x - y = 2x$ for $y$.

First, simplify the equation by moving all $x$ terms to one side:

$3x - y = 2x$

Subtract $2x$ from both sides:

$3x - 2x - y = 0$

This simplifies to:

$x - y = 0$

Now, solve for $y$:

$-y = -x$

Multiply both sides by -1:

$y = x$

So, the solution to the equation is:

$y = x$
