When x is zero the statement is not true.
Here are ten values of x which make the statement true:
2, 3, 4, 5, 6, 7, 8, 9, 10, 11,
there are of course many other values which make the statement true.
An inequality like this can be solved by splitting it into two parts:
9 < 3x 9 < 3x x > 3 
3x < 5x  2 2 < 2x x > 1 
So the complete answer is x > 1
