Answer
The solution to the inequality \( x + 5 > 8 \) is \( x > 3 \).
Solution
To solve the inequality \( x + 5 > 8 \), follow these steps:
### Step 1: Isolate the Variable \( x \)
Subtract 5 from both sides of the inequality to isolate \( x \):
\[
\begin{align*}
x + 5 &> 8 \\
x + 5 - 5 &> 8 - 5 \\
x &> 3
\end{align*}
\]
### Solution
\[
\boxed{x > 3}
\]
### Graphing the Solution
To graph the inequality \( x > 3 \) on a number line:
1. **Draw a Number Line:**
- Represent a horizontal line with evenly spaced marks indicating numbers.
2. **Plot the Boundary Point:**
- Place an open circle (○) at \( x = 3 \) to show that 3 is **not** included in the solution.
3. **Shade the Solution Region:**
- Shade the portion of the number line to the **right** of the open circle at 3, indicating all real numbers greater than 3 are solutions.
**Visualization:**
```
<-------|------○======>
3
```
- The open circle at 3 signifies \( x = 3 \) is not included.
- The arrow and shading to the right of 3 represent all values where \( x > 3 \).
### Summary
- **Inequality Solution:** \( x > 3 \)
- **Graph:** Open circle at 3 with shading to the right on the number line.

Extra Insights
To solve the inequality \( x + 5 > 8 \), start by isolating \( x \). Subtract 5 from both sides: \[ x > 8 - 5 \] This simplifies to: \[ x > 3 \] The solutions to the inequality are all values of \( x \) that are greater than 3. Now, graphing this inequality on a number line, you would draw an open circle at 3 (indicating that 3 is not included in the solution set) and shade to the right of 3 to indicate that all numbers greater than 3 are part of the solution. So the solutions are: \( x > 3 \).
