I'm not sure about the punctuation, but if I understand your words correctly, the equation is:
1/2n-6=1
using reverse order of operations, add six to both sides of the equation:
1/2n-6+6=1+6
1/2n=7
using the multiplication property of equality, multiply both sides of the equation times two:
2(1/2)n=2(7)
simplify:
n=14
check answer by substituting 14 for n in the original equation:
1/2(14)-6=1

One-half of n is written as
or
When they say "diminished by six" they mean subtract 6 from that
What happened to n is that it was divided by 2 first and then 6 was subtracted from the result. They mean
or
To solve this kind of problem you have to "undo" all the evil things that have been done to poor
in reverse order, just like you take off your shoes and socks in the reverse order than you used to put them on.
First you add 6 to each side to get
It simplifies to
Then you multiply both sides by 2, to get
