Question

NEED HELP ASAP PLEASE!!

Answer 1

`( (4)/(4 - x) + (5)/(x - 4) )/( (5)/(x) + (2)/(x - 4) ) =`


`=( (-4)/(x - 4) + (5)/(x - 4) )/( (5(x - 4))/(x(x - 4)) + (2x)/(x(x - 4)) )`


`=( (5-4)/(x - 4) )/( (5(x - 4) + 2x)/(x(x - 4)) )`


`=( (1)/(x - 4) )/( (5x - 20 + 2x)/(x(x - 4)) )`


`=( (1)/(x - 4) )/( (7x - 20)/(x(x - 4)) )`


`=(1)/(x - 4) * (x(x - 4))/(7x - 20)`


`=(x)/(7x - 20)`
