Question
can someone explain what's n+13n=5+n+12
2 Answer

1. User Answers TSO
n+13n=5+n+12
Simplify it
2n+1 = n+4
Add 2n to both sides
1 = 3n+4
Subtract 4 from both sides
3 = 3n
Divide by 3
n = 1 
2. User Answers iGreen
n + 1  3n = 5 + n + 1  2
Combine like terms:
n  3n = 2n
2n + 1 = 5 + n + 1  2
Combine like terms:
5 + 1  2 = 6
2n + 1 = n  6
Subtract 'n' to both sides:
3n + 1 = 6
Subtract 1 to both sides:
3n = 7
Divide 3 to both sides:
n = 2 1/3 or 7/3
