Question 237367
I have a problem of -h is less then or equal to-14 and what I am trying to figure ot is do I need to divide the negative sign so that it's no longer there by h ?

There are two ways to do that.  Here is the first way:

{{{-h<=-14}}}

Add 14 to both sides:

{{{-h+14<=-14+14}}}

{{{-h+14<=0}}}

Add h to both sides:

{{{-h+14+h<=0+h}}}

{{{14<=h}}}

That's the first way.

Now here is the second way. It's shorter but
it requires learning a rule. So learn this rule
so you can use the shorter method.

Rule: If you multiply or divide both sides of an
inequality by a negative number, you must
reverse the direction of the inequality. 

{{{-h<=-14}}}

Now divide both sides by {{{-1}}} and reverse
the direction of the inequality:

{{{(-h)/(-1) >= (-14)/(-1)}}}

{{{h>=14}}}.

----------------

Notice that what we got using the first method

{{{14<=h}}}

is exactly the same as what we got using the
second method

{{{h>=14}}}.
