If x is zero, is the following true?
11x - 9 < 7x + 3 < 6x + 7
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 true.
Here are ten values of x which make the statement true:
2, 1, 0, -1, -2, -3, -4, -5, -6, -7,
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:
|11x - 9 < 7x + 3
4x < 12
x < 3
|7x + 3 < 6x + 7
x < 4
So the complete answer is x < 3
