thank you very much!
thanks!
easiest way to see it is to just test x=1 and x=10, both fail immediately. once you realize LHS is always positive and RHS has to be bigger, positive x only, you can kill it fast. answer is 0, took me 30 sec.
wait, why does LHS always being positive matter here?
What it tests
Your ability to solve and combine linear inequalities and reason about ranges of values.
Common trap
Failing to flip the inequality sign when multiplying or dividing by a negative, or missing an inclusive/exclusive endpoint.
