-14 <= -2c - 2 < -6. Add 2 to all 3 parts of this compound inequality. You will get an equivalent inequality -12 <= -2c < -4. Next step divide by (-2) all parts of this compound inequality. Since you divide by negative number, do not forget to change the inequality signs to the opposite. You will get an equivalent inequality 2 < c <= 6. It is your Answer. The solution to the given inequality is the set of real numbers 2 < c <= 6.
