can someone show me how to do this problem x-xy if x=-2 y=-3 I am just dumb when it comes to this I am studying for My ged and math is my worst subject thanks

Just plug the numbers in for the values, and simplify. For instance:

Evaluate ab + 3c for a = 2, b = -4, c = 5.

You'd plug "2" in for "a", "-4" in for "b", and "5" in for "c", and simplify:

__(2)(-4) + 3(5) = -8 + 15 = 7

Follow the same procedure with your example.

is this correct

x-xy if x=-2 y=-3
(-2)-(-2)(-3)
-2-6=-8

 

[stapel]

Yes. The order of operations says that the multipication must be done first, so you have to handle the -2 times the -3 first, giving you a +6. But then you're subtracting this from the initial -2, giving you -2 - 6, or -8.

Good work!
