Inequality with negative values: Find the interval for the set of x-values that satisfy .

We can use Rule 2 for inequalities and subtract 4 from all 3 terms:

or

Now we can apply Rule 4 for inequalities. Since we need to multiply by -1/3, the direction of the inequalities will be reversed:

or or
