Answer:

X= 5

Step-by-step explanation:

x+4/5=16/x

5x+4/5= 16/x

then calculate the equation solve by quadratic formula you will get the ans. 5

Answer 2

Answer:

$\frac{x + 4}{5} = \frac{16}{ x } \\ {x}^{2 } + 4x = 80 \\ {x}^{2} + 4x - 80 = 0 \\ \\ d = {b}^{2} - 4ac \\ d = 16 \\ x = \frac{ - b + - \sqrt{d} }{2a} \\ x = - \frac{ - 4 - 4}{2} \: \: and \: \: \frac{ - 4 + 4}{2} \\ x = - 4 \: \: and \: \: 0$
