x-120>100-x
The factorial of 5 is 120.
x-120+x>100
Add x to both sides.
2x-120>100
Combine x and x to get 2x.
2x>100+120
Add 120 to both sides.
2x>220
Add 100 and 120 to get 220.
x>\frac{220}{2}
Divide both sides by 2. Since 2 is positive, the inequality direction remains the same.
x>110
Divide 220 by 2 to get 110.
