The inequality is .

Apply distributive property: .

Subtract 7 from each side.

Subtract 3q from each side.

Divide each side by .

The solution set is .

Check:

To check, substitute three different values for q into the original inequality: negative 2, a number less than negative 2, and greater than negative 2.

Let three values are substitute in the original inequality, .

If then      (This is true)

If then      (This is true)

If then             (This is false)

The solution set is .
