-x\geq -9
Subtract 9 from both sides. Anything subtracted from zero gives its negation.
x\leq \frac{-9}{-1}
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
x\leq 9
Fraction \frac{-9}{-1} can be simplified to 9 by removing the negative sign from both the numerator and the denominator.
