If x is zero, is the following true?
5x + 7 < 4x + 2 < x - 10
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:
-6, -7, -8, -9, -10, -11, -12, -13, -14, -15,
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:
|5x + 7 < 4x + 2
x < -5
|4x + 2 < x - 10
3x < -12
x < -4
So the complete answer is x < -5
