8-x\geq 0
Divide both sides by 3. Since 3 is positive, the inequality direction remains the same. Zero divided by any non-zero number gives zero.
-x\geq -8
Subtract 8 from both sides. Anything subtracted from zero gives its negation.
x\leq \frac{-8}{-1}
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
x\leq 8
Fraction \frac{-8}{-1} can be simplified to 8 by removing the negative sign from both the numerator and the denominator.
