| 2x - 3| = 3 - x
=> 2x - 3 = 3-x hoặc 2x - 3 = -3+x
Xét: 2x - 3 = 3-x
=>2x + x = 3+3
=> 3x = 6
=> x = 6:2
=>x = 2
Xét 2x - 3 = -3+x
=> 2x - x = -3 + 3
=> x = 0
Vậy x ∈{ 2 ; 0 }

Tìm x, theo 3 cách:
a) x+1/3=3/6
b) 2x+1/3=3/6
c) 2x-1/4=3/8
Bài 1:Tìm x thuộc Q a,|x + 3/5| - |x - 7/3 |=0
b,2.|3x-1/2| - 3.|x-1/2|=0
c,3.|1/2x - 1| - 5.|3/2x + 1|=0
Tìm x ; y :
a , / 2x-6 / + / x + 3 / = 8
b , / 2x - 1 / + 2x - 5 / = 4
c , / x + 1 / + / x + 2 / + / x + 3 / + / x + 4 / = 5x - 1
Giúp em với ???
Tìm x:
a) |-3x + 4| + |x - 7| - x + 5 = 0
b) |-x+5| + |2x - 3| - |4x+7| = 0
c) |-x + 2| - |2x+4| - |x+3| - 2x + 1 = 0
~Pleaseee helppp meeeee!!!!
Tìm x biết :|x-2|+|3-2x|=2x+1
