To solve for \( f \) in the equation \( 173f - 1 = 1 \), follow these steps:
-
Add 1 to both sides of the equation: \[ 173f - 1 + 1 = 1 + 1 \] \[ 173f = 2 \]
-
Divide both sides by 173: \[ f = \frac{2}{173} \]
None of the provided options (A. 5, B. 6, C. 3, D. 4) are correct, as \( f \) does not equal any of these values. The solution demonstrates that \( f = \frac{2}{173} \) is the accurate answer based on the given equation.
