Answer:

-23

Step-by-step explanation:

Plug in the x and the y into the equation:

5((2)+3)-3(4)^2

On the left side of the equation distribute the 5 to the 2 and the three to get:

(10+15)-3(4)^2

which would give us

(25)-3(4)^2

lets solve the other side now

4^2 is 16 and multiply that by 3 to get 48

so it should look like this:

25-48

=-23
