11 1/9=100/9

first pipe want x m  to fill the tank
second tap want x+5 m to fill the tank

amount of water that fill through the 1st pipe in 1 miniute= \frac{1}{x}
"

 \frac{1}{x} + \frac{1}{x+5} = \frac{100}{9}  \\  \\ 
 \frac{x+5+x}{ x^{2} +5x}= \frac{100}{9}   \\  \\ 
18x+45=100 x^{2} +500x \\  \\ 
100 x^{2} +500x-18x=45 \\ 
100 x^{2} +482x=45 \\ 
100 x^{2} +482x-45=0


then factor it ..

1 5 1
i guess it should be 481x
no how?
plz pick it as the best..
well u did a mistake
