4-2 = ? 3+5 = ?
yes, do you know the answer now?
i think so
what do you have?
what you mean
what did you get for your answer?
2 and 8
No, that is not even the right form of the answer. What happened to the x and y? I don't think you understand the question as well as henkjan thought you did. first of all, do you know how to simplify -(2x-5y) ??? as it says above, you need to "distribute the negative sign" do you know what that means? what do you get by doing that?
um does it stay like that
no, the rule of distribution works like this in general:\[a(x+y)=ax+ay\]for your problem we treat "a" as -1, so we have\[-1*(2x-5y)=-2x+5y\](remember that minus times minus is positive)
ok thank you
I hope you do not think that is the answer above...
Do you just not care to continue, or do you have the answer? If you do, what is it?
