## anonymous 5 years ago n-5 over 2=5 help please forever till i'm done or i will get a F

1. anonymous

when u get equation like this, first thing u do is diminish the fraction by multiply both sides with the amount in denominator.

2. anonymous

multiple by sides by 2 to get n-5=10, add 5 on both sides to get n=10+5=15

3. anonymous

let me try it

4. anonymous

SPACENIGHT DO I ADD 5 TO 15 OR 10 I KNOW I ADD 5 TO 5 I'M CONFUSED

5. anonymous

You add 5 to 10 to get 15.

6. anonymous

add 5 on both sides meant: n-5+5 = 10+5 ---> n=15

7. anonymous

OOOH LOL

8. anonymous

HOW ABOUT $-9+N OVER 4=-7$

9. anonymous

I MEANT N OVER 4 LOL SORRY

10. anonymous

Add 9 on both sides so you get (n/4)=2. Multiple by sides by 4 to get n=8

11. anonymous

multiple both sides*

12. anonymous

WAT!!!!!!!!!!

13. anonymous

$-9 + N \over 4$ = 7

14. anonymous

first, multiply EVERYTHING by 4. like so:

15. anonymous

$4[(-9 + N)/4] = 4[7]$

16. anonymous

This removes the fraction.

17. anonymous

\[-9+N OVER 4 =-7

18. anonymous

oh okay

19. anonymous

anyway you still multiply everything by 4.

20. anonymous

this takes away the fraction, leaving you with -9 + N = 28

21. anonymous

I mean -28

22. anonymous

OK

23. anonymous

add 9 to both sides

24. anonymous

N = 19

25. anonymous

(I mean -19)

26. anonymous

do you understand?

27. anonymous

OK

28. anonymous

need any other help with this type of problem?
