Question

3/x-2 = -2/x-4

Answer 1

\(\dfrac{3}{x-2}=\dfrac{-2}{x-4}\)

\(\Rightarrow3\left(x-4\right)=-2\left(x-2\right)\) (áp dụng tính chất tỉ lệ thức)

\(\Rightarrow3x-12=-2x+4\)

\(\Rightarrow3x+2x=4+12\)

\(\Rightarrow5x=16\)

\(\Rightarrow x=\dfrac{16}{5}\)

Vậy: \(x=\dfrac{16}{5}\)

Answer 2

=>3(x-4)=-2(x-2)

=>3x-12=-2x+4

=>5x=16

=>x=16/5
