Question 490764
<pre>

10a+10 > 9a+22


10a+10 > 9a+22
<u>   -10     -10</u>   Subtract 10 from both sides:

10a    > 9a+12



10a+10 > 9a+22
<u>   -10     -10</u>
10a    > 9a+12
<u>-9a     -9a   </u>   Subtract 9a from both sides
  a    >    12

For set builder notation, put "{a |" before the inequality
and a close bracket "}" after it:

{a | a > 12}

Some people use a colon instead of a slash, like this:

{a : a > 12}
