Answer:

-28

Explanation:

Basically, this question is asking you to substitute the variables (x and y in this case) with numbers to solve the equation. Before we solve, let's replace those variables. So, if x = (-2), and y = 6, then:

5(-2) - 3(6).

We need to solve the equation from left to right. But we can't solve for the subtraction yet, because we need to solve for the multiplication first. So:

5 x (-2) = (-10) and 3 x 6 = 18.

Now we can subtract.

-10 - 18 = (-28).

Let me know if you have any more questions, I hope that this helps.
