12x-24\leq -12\times 20
Multiply both sides by 20. Since 20 is positive, the inequality direction remains the same.
12x-24\leq -240
Multiply -12 and 20 to get -240.
12x\leq -240+24
Add 24 to both sides.
12x\leq -216
Add -240 and 24 to get -216.
x\leq \frac{-216}{12}
Divide both sides by 12. Since 12 is positive, the inequality direction remains the same.
x\leq -18
Divide -216 by 12 to get -18.
