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

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

    n=1.5 or 3/2 is incorrect.

    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 =.... ?

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

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

    combine like terms, 5n+n = 6n

  30. hartnn

    so, 6n +12=-3

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

  32. 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

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

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

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