Answer:.
ANY number that's less than 40 is a solution.
Here's why: 100-2x>20
Divide each side by 2: 50-x>10.
Add x to each side: 50>10+x
Subtract 10 from each side: 40>x .
Here are 3 solutions.
X=0. 100-2x=100. (Greater than 20.)
X=39.5. 100-2x=21 (Greater than 20.)
X= -10. 100-2x=120 (Greater than 20.)
