20w\geq -8\left(-w\right)+144
Use the distributive property to multiply -8 by -w-18.
20w\geq 8w+144
Multiply -8 and -1 to get 8.
20w-8w\geq 144
Subtract 8w from both sides.
12w\geq 144
Combine 20w and -8w to get 12w.
w\geq \frac{144}{12}
Divide both sides by 12. Since 12 is positive, the inequality direction remains the same.
w\geq 12
Divide 144 by 12 to get 12.
