If x = -2 and y = 5, find the value
of the expression 5y - 3x².

=3

Step-by-step explanation:

Because....

what I did first was plug in -2 in the x's place and 5 in the y's place.

So it would look like, 5+5-3-2^2 , then you have to solve that.

Since,

Then, it would be

Add and subtract ( left to right) 5 + 5 - 3 - 4

Finally, your answer is going to be 3.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
