Let's see if x=-4 is a solution for the inequality x-2%3E9.


x-2%3E9 Start with the given inequality.


%28-4%29-2%3E9 Plug in x=-4.


-6%3E9 Evaluate and simplify the left side.


Since the inequality is not true, this means that x=-4 is not a solution.


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



Let's see if x=0 is a solution for the inequality x-2%3E9.


x-2%3E9 Start with the given inequality.


%280%29-2%3E9 Plug in x=0.


-2%3E9 Evaluate and simplify the left side.


Since the inequality is not true, this means that x=0 is not a solution.


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




Let's see if x=15 is a solution for the inequality x-2%3E9.


x-2%3E9 Start with the given inequality.


%2815%29-2%3E9 Plug in x=15.


13%3E9 Evaluate and simplify the left side.


Since the inequality is true, this means that x=15 is a solution.



---------------- Summary ----------------


So the only solution to the inequality x-2%3E9 is x=15
