-3 $\leq$ x $\leq$ 3

Work Step by Step

This is a compound inequality so you have to separate it into two inequalities in order to solve. First inequality: 4x $\leq$ 12 -divide both sides by 4- x $\leq$ 3 Second inequality: -7x $\leq$ 21 -divide both sides by -7- x $\leq$ -3 Put both of the solutions on the same line starting with the lowest number so -3$\leq$ x $\leq$ 3
