Phương trình bạn đưa ra là:

\[
\frac{56800}{x - 9} = 100
\]

=>  \[
56800 = 100(x - 9)
\]

<=> \[
56800 = 100x - 900
\]

=>  \[
56800 + 900 = 100x
\]

<=> \[
57700 = 100x
\]

=> \[
x = \frac{57700}{100} = 577
\]

Vậy \[
x = 577
\]

56800x−9=10056800x−9=100

=>  56800=100(x−9)56800=100(x−9)

<=> 56800=100x−90056800=100x−900

=>  56800+900=100x56800+900=100x

<=> 57700=100x57700=100x

=> x=57700100=577x=57700100=577

Vậy x=577
