To solve the equation \( \frac{7}{4}x = 28 \), follow these steps:
- Multiply both sides of the equation by the reciprocal of \( \frac{7}{4} \), which is \( \frac{4}{7} \):
\[ x = 28 \cdot \frac{4}{7} \]
- Simplify the right side:
\[ x = 28 \cdot \frac{4}{7} = 4 \cdot 4 = 16 \]
Thus, the solution is:
\[ x = 16 \]
