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

First, calculate 2y:

2y = 2 * 3 = 6.

Next, substitute the value of x into the expression:

Then, the expression becomes:

2y - x = 6 - (-2).

Now, simplify the equation, which involves subtracting a negative:

6 - (-2) is the same as 6 + 2, resulting in:

6 + 2 = 8.

Thus, the value of the expression 2y - x is 8.

This confirms that the correct answer is indeed 8, aligning with the option initially selected.
