The mystery number is 33.
Solución
Let's solve the problem step by step.
**Problem Statement:**
A mystery number increased by 15 is 48.
**Let's define the mystery number as:**
\( x \)
**According to the problem:**
\[ x + 15 = 48 \]
**To find \( x \), subtract 15 from both sides of the equation:**
\[
\begin{align*}
x + 15 &= 48 \\
x &= 48 - 15 \\
x &= 33
\end{align*}
\]
**Answer:**
The mystery number is **33**.

To solve this, you simply need to subtract 15 from 48. So, the mystery number is 48 - 15, which equals 33. This easy arithmetic is a great reminder of how often we can break down problems to find simple solutions! In real life, such equations can relate to budgeting or shopping. For instance, if you know the total cost of items after adding a tax or discount, you can easily find out what the original price was by reversing the calculation, much like solving for our mystery number!
