-n\geq 12-18
Subtract 18 from both sides.
-n\geq -6
Subtract 18 from 12 to get -6.
n\leq \frac{-6}{-1}
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
n\leq 6
Fraction \frac{-6}{-1} can be simplified to 6 by removing the negative sign from both the numerator and the denominator.
