If x is zero, is the following true?
2x + 13 < 5x + 1 < 10x  34
In the back of your books write down at least 10 values of x which satisfy this inequality statement.
"<" means "is less than"

When x is zero the statement is not true.
Here are ten values of x which make the statement true:
8, 9, 10, 11, 12, 13, 14, 15, 16, 17,
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:
2x + 13 < 5x + 1 12 < 3x x > 4 
5x + 1 < 10x  34 35 < 5x x > 7 
So the complete answer is x > 7
