Question

Answer 1

g: =>2x-3<=0

=>x<=3/2

h: =>3-x>=0

hay x<=3

Answer 2

g,\(\Leftrightarrow2x-3-3+2x=0\)

\(\Leftrightarrow4x-6=0\)

\(x=\dfrac{6}{4}=\dfrac{3}{2}\)

Answer 3

g, Với x =< 3/2 

TH1 : \(2x-3=3-2x\Leftrightarrow4x=6\Leftrightarrow x=\dfrac{3}{2}\left(tm\right)\)

TH2 : \(3-2x=3-2x\)* vô lí *

h, Với x =< 3 

TH1 : \(3-x=3-x\)* vô lí *

TH2 : \(x-3=3-x\Leftrightarrow2x=6\Leftrightarrow x=3\)(tm)
