-3x\leq -4
Subtract 4 from both sides. Anything subtracted from zero gives its negation.
x\geq \frac{-4}{-3}
Divide both sides by -3. Since -3 is negative, the inequality direction is changed.
x\geq \frac{4}{3}
Fraction \frac{-4}{-3} can be simplified to \frac{4}{3} by removing the negative sign from both the numerator and the denominator.
