Answer:

-38

Explanation:

-8.x – 3y

x = 4

y = -2

Since we have the value for x and y we can use that and substitute it into the expression

-8(4) - 3 (-2)

-32 - 6

When you add 2 negative numbers (or subtract them) they will give you a bigger number so think of it as adding 2 positive numeber, but then putting a negative sign in the beginning of it.

-32 - 6

-38

Hope this helped!
