Answer
All real numbers \( a \) less than \( \frac{1}{2} \).
\[
a < \frac{1}{2}
\]
Solution
To solve the inequality \( 5 > 12a - (3 - 4a) \) and graph the solution, follow these steps:
### Step 1: Simplify the Inequality
Start by simplifying the right-hand side of the inequality.
\[
5 > 12a - (3 - 4a)
\]
Distribute the negative sign inside the parentheses:
\[
5 > 12a - 3 + 4a
\]
Combine like terms (\(12a + 4a\)):
\[
5 > 16a - 3
\]
### Step 2: Isolate the Variable Term
Add 3 to both sides to move the constant term to the left side:
\[
5 + 3 > 16a
\]
\[
8 > 16a
\]
### Step 3: Solve for \( a \)
Divide both sides by 16 to isolate \( a \):
\[
\frac{8}{16} > a
\]
Simplify the fraction:
\[
\frac{1}{2} > a
\]
This can also be written as:
\[
a < \frac{1}{2}
\]
### Step 4: Graph the Solution
To graph the solution \( a < \frac{1}{2} \) on a number line:
1. **Draw a number line** with relevant points, including \( \frac{1}{2} \).
2. **Place an open circle** at \( \frac{1}{2} \) to indicate that \( \frac{1}{2} \) is **not** included in the solution (since the inequality is strictly "<").
3. **Shade the region to the left** of \( \frac{1}{2} \) to represent all real numbers less than \( \frac{1}{2} \).
Here is a visual representation:
```
<----|----------|----------|----------|---->
0 1/2 1 3/2
●---------------->
```
- **●** represents the open circle at \( \frac{1}{2} \).
- The arrow pointing to the left indicates all values less than \( \frac{1}{2} \).
### Final Answer
All real numbers \( a \) less than \( \frac{1}{2} \).
\[
a < \frac{1}{2}
\]
