**Ms. Sue**, Tuesday, October 19, 2010 at 5:58pm9n +12=6n +54

9n - 6n = 54 - 12

3n = 42

n = 42/3

n = 14

**Anonymous**, Tuesday, October 19, 2010 at 6:00pm9n + 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 .
