Question

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

Answer 1

Ta có:\(2\left|x-3\right|=\dfrac{3}{4}\)

      \(\Leftrightarrow\left|x-3\right|=\dfrac{3}{8}\)

      \(\Leftrightarrow\left[{}\begin{matrix}x-3=\dfrac{3}{8}\\x-3=\dfrac{-3}{8}\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}x=\dfrac{27}{8}\\x=\dfrac{21}{8}\end{matrix}\right.\) 

Answer 2

2/x-3/=3/4

/x-3/= 3/4 : 2

/x-3/= 3/8

=> x-3 = +- 3/8

 x-3 = 3/8

x       = 3/8+3

x       = 27/8

x-3    = -3/8

x       = -3/8+3

x       = -21/8

=> xE{ 27/8;-21/8}
