\(\frac{-1}{x-2}=\frac{x-2}{-9}\)ĐKXĐ: \(x\ne2\)

\(\Rightarrow\left(x-2\right)\left(x-2\right)=-1\cdot\left(-9\right)\)

\(\Rightarrow\left(x-2\right)^2=9\)

\(\Rightarrow\orbr{\begin{cases}x-2=3\\x-2=-3\end{cases}\Rightarrow\orbr{\begin{cases}x=5\\x=-1\end{cases}}}\)( thỏa mãn ĐKXĐ)

vậy..........

1,2 x Y + 2,5 = 4,2 + 1,36

1,2 x Y + 2,5 = 5,56

1,2 x Y = 5,56 - 2,5

1,2 x Y = 3,06 

Y = 3,06 : 1,2

Y = 2,55

vậy Y = ...

1,2 x Y + 2,5 = 4,2 + 1,36

1,2 x Y + 2,5 = 5,56

1,2 x Y = 5,56 - 2,5

1,2 x Y = 3,06 

Y = 3,06 : 1,2

Y = 2,55

mình viết bừa :) tích cho mình nha

1,2 x y + 2,5 = 4,2 + 1,36 

1,2 x y + 2,5 = 5,56

1,2 x y          = 5,56 - 2,5 

1,2 x y          = 3,06

y                   = 3,06 : 1,2 

y                   2,55

Bài toán đâu vậy bn

bài đâu bạn

để tớ thử tìm xem

mn giúp mink 

mn giúp mink nha

=>(-4) x y -5= -9

=>(-4) x y= -4

=> y=1
