To solve the equation \( \frac{3}{4}x - \frac{1}{2} = 7 \), we can follow these steps:
1. **Add \( \frac{1}{2} \) to both sides**:
\[
\frac{3}{4}x = 7 + \frac{1}{2}
\]
2. **Convert 7 to a fraction with a common denominator** (which is 2):
\[
7 = \frac{14}{2}
\]
So,
\[
\frac{3}{4}x = \frac{14}{2} + \frac{1}{2} = \frac{15}{2}
\]
3. **Multiply both sides by the reciprocal of \( \frac{3}{4} \)**, which is \( \frac{4}{3} \):
\[
x = \frac{15}{2} \cdot \frac{4}{3}
\]
4. **Multiply the fractions**:
\[
x = \frac{15 \cdot 4}{2 \cdot 3} = \frac{60}{6}
\]
5. **Simplify**:
\[
x = 10
\]
So, the solution is:
\[
\boxed{10}
\]
