\(x+\dfrac{2}{3}=x-\dfrac{2}{2}\)
\(x+\dfrac{2}{3}=x-1\)
\(x-x=1-\dfrac{2}{3}\)
\(0=\dfrac{3}{3}-\dfrac{2}{3}\)
\(0=\dfrac{1}{3}\) (vô lí)
Vậy không tìm được giá trị x.
bài 1 : tìm x, biết:
A) X/3 - 1/2 = 1/5 B) x/5 + 1/2 = 6/10 c) x +3 /15 = 1/3 d) x -14/4 =1/4
đ) 1/2 x + 1/2 =5/2 n) -2/3 1/3 ( 2x -5 )=3/2 i) ( 3x -1) ( -1/2 x +5 ) =0 j) x-2/4 = 5+x/3
q) 3/x + 5 = 15% p) | x - 1/3 =5/6 m) 2| 1/2 x - 1/3 | - 3/2 = 1/4
z) ( 4,5 - 2 x) . ( -11/7) = 11/14 y) ( x/7 + 0,25 ) = -1/28
giup minh nhé
mai nộp rồi

Bài 1:Tìm x
a, \(2.x-\frac{1}{2}=\frac{5}{4}-\frac{1}{2}.x\)
b, \(\frac{3}{4}-\frac{5}{2}.x=2-3.x\)
c, \(\frac{3}{2}.\left(x-\frac{1}{3}\right)-2\left(x-\frac{1}{2}\right)=3\)
d, \(\frac{4}{3}.\left(x-\frac{3}{2}\right)-3.\left(\frac{1}{3}.x+1\right)=6\)
-5.(x+1/5)-1/2(x-2/3)=3/2.x-5/6
a. 2/3x-1/2=1/10
b. 39/7:x=13
c. (14/5x-50):2/3=51
d. (x+1/2)(2/3-2x)=0
e. 2/3x-1/2x=5/12
g. (x.44/7+3/7)11/5-3/7=-2
h. x.13/4+(-7/6)x-5/3=5/12
i.93/17:x+(-4/17):x+22/7:52/3=4/11
j. 17/2-|2x-3/4|=-7/4
k. (x+1/5)^2+17/25=26/25
l. -32/27-(3x-7/9)^3=-24/27
Tìm x
p,-5 (x + 1/5 ) - 1/2( x - 2/3 ) = 3/2x - 5/6
q, 3(x - 1/2 ) - 5(x + 3/5 ) = -x+1/5
m, 3(3x - 1/2 )3 + 1/9 = 0
