10a+10 > 9a+22
10a+10 > 9a+22
-10 -10 Subtract 10 from both sides:
10a > 9a+12
10a+10 > 9a+22
-10 -10
10a > 9a+12
-9a -9a 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}
