## Elementary Algebra

The solution set is {x|x $\gt$ -6} , or (-6,$\infty$) in interval notation.
We use the properties of inequalities to solve this inequality. -3x - 6 $\lt$ 12 -3x $\lt$ 18 Divide both sides by -3. (Remember, multiplying or dividing both sides of an inequality by a negative number reverses the sense of the inequality.) x $\gt$ -6 The solution set is {x|x $\gt$ -6} , or (-6,$\infty$) in interval notation.
