To solve the equation \( \frac{17}{3f} - 1 = 1 \), follow these steps:
-
Add 1 to both sides of the equation: \[ \frac{17}{3f} = 2 \]
-
Multiply both sides by \( 3f \): \[ 17 = 2 \cdot 3f \] \[ 17 = 6f \]
-
Divide both sides by 6: \[ f = \frac{17}{6} \]
Since \( \frac{17}{6} \) is approximately 2.8333, it does not match any of the provided responses (5, 3, 4, or 6). Thus, the correct value of \( f \) is not among the given options.
