Question 105092
So this will be an inequality.
We form the inequality as {{{135 < 11n < 140}}}
We can do this in two ways:

The long way is by splitting it up into two inequalities.
This will be:
{{{135  <  11n}}} and {{{11n  <  140}}}
Then we solve it as if we are solving an equation.
{{{(135)/11  <  (11n)/11}}} and {{{(11n)/11  <  (140)/11}}}
{{{135/11 < n}}} and {{{n < 140/11}}}

There, we have it.
{{{135/11 < n < 140/11}}}


The short way will be:
{{{135  <  11n  <  140}}}
Just divide all sides by 11.
{{{135/11 < 11n/11 < 140/11}}}
There, we're done.
{{{135/11 < n < 140/11}}}



Take note that when dividing inequalities with negative integers, the signs should be reversed.

Thank you.
