1-104.

Zaria wants you to solve this puzzle: “I am thinking of a number. If you divide my number by $\mathit{2}$ and subtract $\mathit{4}$, you will get $\mathit{2}$. What is my number?” Show how you know your answer is correct.

Try a number. For example, $100$.
$100\div2-4$
$50-4$
$46$ (too big)

Since it is too big, try a different number.
