## love43 3 years ago (4x + 3y) - (2x -5y) (Hint: Remember to distribute the negative to the second set of parentheses.)

4-2 = ? 3+5 = ?

2. love43

2 8

3. TuringTest

yes, do you know the answer now?

4. love43

i think so

5. TuringTest

what do you have?

6. love43

what you mean

7. TuringTest

8. love43

2 and 8

9. TuringTest

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?

10. love43

um does it stay like that

11. TuringTest

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)

12. love43

ok thank you

13. TuringTest

I hope you do not think that is the answer above...

14. love43

no lol

15. TuringTest

Do you just not care to continue, or do you have the answer? If you do, what is it?
