to eliminate the fraction, you can multiply by 3 on both sides.

- anonymous

multiply 3 by what?

- hartnn

multiply both sides of the equation by 3

- anonymous

@Best_Mathematician that isn't exatly the answer i was looking for...

- anonymous

so 5 and 12?

- anonymous

my mistake here's the correction
5n + 12 + n = -3
6n = -15
n = -5/2

- anonymous

1.5?

- anonymous

do you have to simplify that?

- hartnn

n=1.5 or 3/2 is incorrect.

- anonymous

but theres no such thing as 1.5 here :(

- hartnn

do you want to solve it on your own, or just want an answer ?

- anonymous

yeahh thats what i was thinking, it cant be right :/

- anonymous

i need to know the steps so i can do it on my own you guys are just throwing answers or these problems of how you think it should be solved. its just confusing to me

- hartnn

i know, right!
if you multiply each term of that equation by 3, what u get ?
3* (1/3)* (5n+12) =...?
3* (1/3)* n =...?
-3*3 =.... ?

- hartnn

*last line should be -1*3=...?

- anonymous

-3?

- hartnn

thats right side, what about left side of = ?

- anonymous

umm 3*5?

- anonymous

15

- anonymous

sorry i am just terrible at math

- hartnn

3* (1/3)* (5n+12) =5n+12
3* (1/3)* n =n
got this ?

sorry i am just terrible at drawing :P

- anonymous

haha no problem! :D

- anonymous

so i subtract 5 from twelve here?

- anonymous

7 ?

- hartnn

|dw:1362988334714:dw|
so, you are left with simple linear equation :
5n+12+n = -3

- hartnn

you can't subtract 5 from 12...there is 'n' attached to 5

- hartnn

combine like terms,
5n+n = 6n

- hartnn

so, 6n +12=-3

- anonymous

oh, so you divide that? i thought you have to subtract because it is opposite of addition :P

- hartnn

now , subtract 12 from both sides, (because subtraction is opposite of addition)
so,
6n +12-12 = -3-12
6n = -15
now just divide by 6

- anonymous

-2.5

- hartnn

because division is opposite of multiplication,
...yes, thats correct :)

- anonymous

hmm thanks for the help so far! :) so how do you make that a fraction?

- hartnn

6n = -15
n = -15/6 = -3*5 /(3*2)
3 cancels out.
n = -5/2

- anonymous

this will take me a while to learn but i really dont want to waste your time..thank you for this, i will look over it because its got all the help i need :) so thanks :D
