Answer: x is less than 20
Explanation:
We need to get x by itself, we can do that by multiplying 1/2 by its reciprocal, 2/1. What we do to one side we have to do to the other, so we need to multiply 10 (2/1)
Now we have our answer, x is less than 20
We can check our work by substituting x for anything less than 20.
