To solve the inequality \(\frac{x}{5} > -3\), we will first isolate \(x\).
1. Multiply both sides by 5 to eliminate the fraction. Since 5 is positive, the direction of the inequality will remain the same:
\[
x > -3 \times 5
\]
\[
x > -15
\]
Now that we have solved the inequality, we can summarize the solution:
\[
x > -15
\]
### Graphing the Solution
To graph the inequality \(x > -15\), you can use a number line:
1. Draw a horizontal line and mark a point at \(-15\).
2. Since the inequality is strict (\(>\)), use an open circle at \(-15\).
3. Shade the region to the right of \(-15\), indicating all numbers greater than \(-15\).
### Checking the Solution
To check if the solution is correct, you can substitute a number greater than \(-15\) into the original inequality. For example, let's use \(x = -10\):
\[
\frac{-10}{5} > -3
\]
\[
-2 > -3 \quad \text{(True)}
\]
Now, let's check a number that is not in the solution set (less than \(-15\)), such as \(x = -20\):
\[
\frac{-20}{5} > -3
\]
\[
-4 > -3 \quad \text{(False)}
\]
Thus, the solution \(x > -15\) is confirmed to be correct.
### Final Answer
- The inequality is:
\[
x > -15
\]
- For your response box, select "greater than".
