Lösungsweg:
\( \frac{1800}{m} + 10 = \frac{1800}{m-6} \) mal (m-6)
\( \frac{1800 (m-6)}{m} + 10 (m-6) = 1800 \) gemeinsamer Nenner
\( \frac{1800 (m-6) + 10 (m-6) m }{m} = 1800 \) mal m
\( 1800 (m-6) + 10 (m-6) m = 1800 m \) ausmultiplizieren
\( 10m^2 - 60 m - 10800 = 0 \) Mitternachtsformel
\( m = 36 \)
