Question

( x - 3 ) / 3 = 12 / ( x - 3 )

ai nhanh mik tick nha

Answer 1

x =9 nha , tích mh đi 

Answer 2

\(\frac{x-3}{3}=\frac{12}{x-3}\)

\(\Rightarrow\left(x-3\right).\left(x-3\right)=36\)

\(\Rightarrow\left(x-3\right)^2=6^2;\left(-6\right)^2\)

\(\Rightarrow\orbr{\begin{cases}x-3=6\\x-3=-6\end{cases}}\)

\(\orbr{\begin{cases}x=9\\x=-3\end{cases}}\)

Vậy x=9;-3
