To find the inverse of the function \( f(x) = \frac{5x - 6}{x - 1} \), we need to follow these steps:

### Step 1: Replace \( f(x) \) with \( y \).
\[
y = \frac{5x - 6}{x - 1}
\]

### Step 2: Swap \( x \) and \( y \), then solve for \( y \).
\[
x = \frac{5y - 6}{y - 1}
\]

### Step 3: Multiply both sides by \( y - 1 \) to eliminate the denominator.
\[
x(y - 1) = 5y - 6
\]
\[
xy - x = 5y - 6
\]

### Step 4: Group all terms with \( y \) on one side.
\[
xy - 5y = x - 6
\]

### Step 5: Factor out \( y \) on the left-hand side.
\[
y(x - 5) = x - 6
\]

### Step 6: Solve for \( y \).
\[
y = \frac{x - 6}{x - 5}
\]

Thus, the inverse of \( f(x) \) is:
\[
f^{-1}(x) = \frac{x - 6}{x - 5}
\]
