Solve each inequality the same way you would solve an equality. The only difference is that if you have to multiply or divide by a negative number, the inequality sign changes direction.

take each inequality separately, then you'll have two inequalities

$\displaystyle -3\leq 3x-2$ and $\displaystyle 3x-2\leq -1$

now use rules for inequlities to separate x, so eventually you'll get two possible ranges for x
