To solve for \( x \), we need to isolate it on one side of the equation. The equation is:
\[
\frac{3}{4} x = 12
\]
Step 2: Multiply both sides by the reciprocal of \( \frac{3}{4} \)
The reciprocal of \( \frac{3}{4} \) is \( \frac{4}{3} \). Multiply both sides of the equation by \( \frac{4}{3} \) to solve for \( x \):
\[
\frac{4}{3} \cdot \frac{3}{4} x = 12 \cdot \frac{4}{3}
\]
Step 3: Simplify the equation
Simplify the left side of the equation:
\[
x = 12 \cdot \frac{4}{3}
\]
\[
x = 16
\]
