To solve the equation
\[
\frac{1}{6} = \frac{1}{2} z - \frac{1}{4},
\]
we'll first isolate \( z \).
1. Add \( \frac{1}{4} \) to both sides of the equation:
\[
\frac{1}{6} + \frac{1}{4} = \frac{1}{2} z.
\]
2. To add \( \frac{1}{6} \) and \( \frac{1}{4} \), we need a common denominator. The least common multiple of 6 and 4 is 12. We can rewrite the fractions:
\[
\frac{1}{6} = \frac{2}{12}, \quad \frac{1}{4} = \frac{3}{12}.
\]
Now, rewriting the left side:
\[
\frac{2}{12} + \frac{3}{12} = \frac{5}{12}.
\]
So we have the equation:
\[
\frac{5}{12} = \frac{1}{2} z.
\]
3. Next, to eliminate the fraction on the right side, multiply both sides of the equation by 2:
\[
2 \cdot \frac{5}{12} = z.
\]
4. This simplifies to:
\[
\frac{10}{12} = z.
\]
5. Now, simplify \( \frac{10}{12} \):
\[
z = \frac{5}{6} \quad \text{(after dividing both numerator and denominator by 2)}.
\]
Thus, the value of \( z \) is
\[
\boxed{\frac{5}{6}}.
\]
\[
\frac{1}{6} = \frac{1}{2} z - \frac{1}{4},
\]
we'll first isolate \( z \).

\frac{1}{6} + \frac{1}{4} = \frac{1}{2} z.
