Solve the formula for the given variable. \[ Z=\frac{9}{f-s} \] Solve for \( f \), then solve for \( s \). \( f=\square \) (Simplify your answer.)

Solve the equation \( Z=\frac{9}{f-s} \). Solve the equation by following steps: - step0: Solve for \(f\): \(Z=\frac{9}{f-s}\) - step1: Swap the sides: \(\frac{9}{f-s}=Z\) - step2: Cross multiply: \(9=\left(f-s\right)Z\) - step3: Simplify the equation: \(9=Z\left(f-s\right)\) - step4: Swap the sides: \(Z\left(f-s\right)=9\) - step5: Divide both sides: \(\frac{Z\left(f-s\right)}{Z}=\frac{9}{Z}\) - step6: Divide the numbers: \(f-s=\frac{9}{Z}\) - step7: Move the constant to the right side: \(f=\frac{9}{Z}+s\) - step8: Add the terms: \(f=\frac{9+sZ}{Z}\) - step9: Simplify: \(f=\frac{9+Zs}{Z}\) Solve the equation \( Z=\frac{9}{f-s} \). Solve the equation by following steps: - step0: Solve for \(s\): \(Z=\frac{9}{f-s}\) - step1: Swap the sides: \(\frac{9}{f-s}=Z\) - step2: Cross multiply: \(9=\left(f-s\right)Z\) - step3: Simplify the equation: \(9=Z\left(f-s\right)\) - step4: Swap the sides: \(Z\left(f-s\right)=9\) - step5: Divide both sides: \(\frac{Z\left(f-s\right)}{Z}=\frac{9}{Z}\) - step6: Divide the numbers: \(f-s=\frac{9}{Z}\) - step7: Move the constant to the right side: \(-s=\frac{9}{Z}-f\) - step8: Subtract the terms: \(-s=\frac{9-fZ}{Z}\) - step9: Change the signs: \(s=\frac{-9+fZ}{Z}\) - step10: Simplify: \(s=\frac{-9+Zf}{Z}\) The solution for \( f \) is \( f=\frac{9+Zs}{Z} \) and the solution for \( s \) is \( s=\frac{-9+Zf}{Z} \).
