If x=3, y=-4, and z=2, what is the value of 2x-y?

-10

To find the value of $2x - y$ when $x = 3$ and $y = -4$, we start by substituting the given values into the expression.

First, calculate $2x$:

2x = 2(3) = 6

Next, substitute the value of $y$:

2x - y = 6 - (-4)

Subtracting a negative number is the same as adding its positive:

6 - (-4) = 6 + 4 = 10

Thus, the value of $2x - y$ is 10. This confirms that the correct answer is indeed the one that corresponds to this calculation, which is 10.
