Can someone please explain how to do this problem: 7n5=10n+13

Pre Algebra 
MIKE,
subtract 7n to the other side
AND subtract 13 to the other side
and also divide 3 to the other side,so
7n5=10n+13
5=10n7n +13
513=10n7n
18=3n
n=6

Pre Algebra 
Lisa,
Add 5 to both side
7n=10n+18
Then subtract 10n
3n=18
Finally divide 3 on both sides
n=6
