5x-9>11
Transpose -9 in the other side, thus changing its negative sign into positive
5x>11+9
5x>20
Divide both side by 5 in order to get the value of x
(5x/5)>(20/5)
x>4
The inequality sign does not flip since the rule implies that you only flip the inequality sign whenever you divide or multiply by a negative number.
therefore the final answer is
x>4, read as X is greater than 4.
