Heya mate,

Here is your answer,. ⬇️⬇️

{ANSWER :-}

___________

 <i> (x - 8)(480/x + 3) = 480

=> 480 + 3x - 3840/x - 24 = 480

=> 3x - 3840/x = 24

=> 3x^2 - 3840 = 24x

=> 3x^2 - 24x - 3840 = 0

=> x^2 - 8x - 1280 = 0

=> x^2 - 40x + 32x - 1280 = 0

=> x(x - 40) + 32(x - 40) = 0

=> (x - 40)(x + 32) = 0

=> x = 40, (-32)

➡️ Hence, x = 40, ( - 32)
