To solve the equation
\[
\frac{3(x - 5)}{4} - x = 1 - \frac{x}{8},
\]
we first eliminate the fractions by finding a common denominator. The least common multiple of the denominators (4 and 8) is 8. We can multiply the entire equation by 8 to eliminate the fractions:
\[
8 \left(\frac{3(x - 5)}{4}\right) - 8x = 8\left(1 - \frac{x}{8}\right).
\]
This simplifies to:
\[
2 \cdot 3(x - 5) - 8x = 8 - x.
\]
Now, distributing on the left side:
\[
6(x - 5) - 8x = 8 - x.
\]
Distributing the 6:
\[
6x - 30 - 8x = 8 - x.
\]
Combining like terms on the left side gives:
\[
-2x - 30 = 8 - x.
\]
Now, add \(x\) to both sides:
\[
-2x + x - 30 = 8,
\]
which simplifies to:
\[
-x - 30 = 8.
\]
Next, add 30 to both sides:
\[
-x = 38.
\]
Finally, multiply both sides by -1:
\[
x = -38.
\]
Thus, the solution to the equation is
\[
\boxed{-38}.
