#n>=17#

Explanation:

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!
