Evaluate 2x + xy + 2-3 for x=-9, y=-5, and
z=-3.

Hi! Keep in mind there is no z in the equation so the question might trick you!

The answer is 26

Here is the process:

1. Replace the variables with the numbers they gave you.

2(-9)+ (-9)(-5)+ 2-3

2. Next evaluate it. I got 45 because a negative multiplied by a negative makes a positive.

* PEMDAS states you addition and then subtraction but it could vary based on the equation.

In this equation you have to do addition first.

-18+ 45+2-3

27+2-3

29-3

26

I hope this helps! Have a great day :)
