9n +12=6n +54 what is n and how do you get it

    9n +12=6n +54

    9n - 6n = 54 - 12
    3n = 42
    n = 42/3
    n = 14

    9n + 12= 6n =54
    -6n -6n

    3n + 12=54
    -12 -12

    3n=42
    n= 14
    what you did was take 6n and subtract it from both sides (from 9n & 6n) you get 3n and 7 & -6 cancel because of opposite signs and u are left with 3n+ 12=54 , then you subtract 12 from both sides again & 12 & -12 cancel because of opposite signs & 54-12 is 42 & you are left with 3n=42 and then divided 3 by 42 and 3n and n equals 12 .
