19+18k\leq 1
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
18k\leq 1-19
Subtract 19 from both sides.
18k\leq -18
Subtract 19 from 1 to get -18.
k\leq \frac{-18}{18}
Divide both sides by 18. Since 18 is positive, the inequality direction remains the same.
k\leq -1
Divide -18 by 18 to get -1.
