$n>=17$

So, let's first interpret this equation. Here's it in math terms:

$6-5+n>=18$

Let's put it into words
Six minus five plus n is greater than or equal to eighteen.

So, let's first solve both sides until we can't solve them anymore.

$6-5+n$
$1+n$

We can't simplify $1+n$ any further because we don't know $n$ . And the other side of the equation, $18$ cannot be solved any more either.

So now we have

$1+n>=18$

Next, we want to subtract $1$ from both sides of the equation. So

$1+n-1 >= 18-1$
$n+(1-1)>=17$
$n>=17$

And that's our answer. N can be any number greater than or equal to seventeen.

Cheers!
