Solución
To find the other number when the sum of two numbers is 20 and one of them is 8, you can use the following steps:
1. **Understand the Problem:**
- **Total Sum:** 20
- **Known Number:** 8
- **Unknown Number:** Let's denote it as **x**
2. **Set Up the Equation:**
\[
\text{Known Number} + \text{Unknown Number} = \text{Total Sum}
\]
\[
8 + x = 20
\]
3. **Solve for the Unknown Number (x):**
Subtract 8 from both sides of the equation to isolate **x**:
\[
x = 20 - 8
\]
\[
x = 12
\]
4. **Conclusion:**
The other number is **12**.

To find the other number, you simply subtract the known number from the total sum. So, you'll take the sum of 20 and subtract 8 from it. That means the other number is 20 - 8, which equals 12. A simple way to remember this is to visualize two friends heading to a party carrying a total of 20 balloons, and one friend has 8. You just figure out how many balloons the other friend is carrying! Now, if you ever find yourself confused in problems like this, just remember to write down what you know and what you need to find out. Mistakes often happen when we skip this step, so decoding the problem clearly can save you from unnecessary hiccups!
