Pasos de solución

9 sinh (x) - 5 cosh (x) = 15

Re-escribir usando identidades trigonométricas

9 \cdot \frac{e ^{x} - e ^{- x}}{2} - 5 \cdot \frac{e ^{x} + e ^{- x}}{2} = 15

9 \cdot \frac{e ^{x} - e ^{- x}}{2} - 5 \cdot \frac{e ^{x} + e ^{- x}}{2} = 15 : x = ln (\frac{15 + 281}{4})

x = ln (\frac{15 + 281}{4})
