10<=x/2+21
-x/2<=21-10
-x/2<=11
-x<=2*11
-x<=22
x>=-22 ans. note the sign change when dividing by a negative value.
Proof:
Let x=-21.9
10<=-21.9/2+21
10<=-10.95+21
10<=10.05

if you have "Ten is at most", means ten is less and equal to
the sum of one-half of a number is 1%2F2 of a number x and 21, which is %28x%2B21%29%2F2
then you put all together as: 10%3C=%28x%2B21%29%2F2
