To solve the equation
\[ \frac{f - 60}{-4} = -5, \]
we will start by isolating \( f \).
- Multiply both sides by -4 to eliminate the denominator:
\[ f - 60 = -5 \times -4. \]
- Calculate the right side:
\[ f - 60 = 20. \]
- Now, add 60 to both sides to isolate \( f \):
\[ f = 20 + 60, \] \[ f = 80. \]
Thus, the solution is:
\[ f = 80. \]
