Find the exact solutions of the given equation.
y=15tan(7x+4), for x in (−47−π14,−47+π14)y=\frac15\tan\left(7x+4\right),\text{ for }x\text{ in }\left(-\frac47-\frac{\pi}{14},-\frac47+\frac{\pi}{14}\right)y=51tan(7x+4), for x in (−74−14π,−74+14π)
x=17[tan−1(5y)+4]x=\frac17[\tan^{-1}(5y)+4]x=71[tan−1(5y)+4]
x=7[tan−1(5y)−4]x=7[\tan^{-1}(5y)-4]x=7[tan−1(5y)−4]
x=17[tan−1(5y)−4]x=\frac17[\tan^{-1}(5y)-4]x=71[tan−1(5y)−4]
x=7[tan−1(5y)+4]x=7[\tan^{-1}(5y)+4]x=7[tan−1(5y)+4]
