1. The problem asks to solve the inequality $x > 20$. 2. This is a simple inequality where we want to find all values of $x$ that are greater than 20. 3. The solution set is all real numbers $x$ such that $x > 20$. 4. In interval notation, this is written as $(20, \infty)$. 5. This means any number larger than 20 satisfies the inequality. Final answer: $x > 20$ or $(20, \infty)$.
