Bài 1: Tìm x
x-7/12.x=5/24-3/8.x
(x-1/2).(-3-x/2)=0
x-3/-2=-8/x-3
=) (x-3).(x-3)=(-2).(-8)
(x-3) mũ 2 =16
bài 3:
a) x - 3/4 = 6 x 3/8 b) 7/8 : x = 3 - 1/2 c) x + 1/2 x 1/3 = 3/4
d) 3/2 x 4/5 - x = 2/3 e) X x 3 1/3 = 3 1/3 : 4 1/4 f) 5 2/3 : x = 3 2/3 - 2 1/2

tìm x
a) -1/8 = 3/x b) x/3 = 3/x c)3/4 . x = 1 và 1/2
d) x - 3/10 = 7/15 : 3/5 e) -4/7 - x = -8/3 . 3/7
f) 4/7 . x - 2/3 = 1/5 g) 2/3 + 1/3 : 3 x = 1/5
h) 2/9 - 7/8 x=1/3 j) (2 và 4/5 x - 50) : 2/3 = 51
7-(2x-1/3)^2=3
(2x+1/3)^2-3/8=1/8
12:[29-(x-2/3)^2]=3
(3x-1/2)^3+8/3=29/9-14/27
2(2x-1/3)^2+4/3=5/6+13/18
Tìm X
1.Tim x biết x - 252525 * 3/2 + 3/5 - 3/7 / 3/2 + 1/5 - 1/7 =7/8
2. 9/8 - 9/8 * 2/5 + 2/6 - 2/7 / 3/5 + 3/6 - 3/7 - X = 1
a/ (x-1/2)mũ 3 = -8 e/(x-5/2) mũ 3=-1/8
b/ (x-1/3)mũ 3=27/8 f/(x-1/8) mũ 3=-8/125
c/ (x-5/2)mũ 3=-8/27 giúp mk vs!!!!!!!!!! plsssss
d/ (x-1/3) mũ 3=8/27
5/8-(x+3/4)=7/6
(x-3/4)+3/2+11/3
(x+1/2)-5/8=2
11/2-(4/5+x)=2-1/3
5/8-(x+3/4)=7/6
(x-3/4)+3/2+11/3
(x+1/2)-5/8=2
11/2-(4/5+x)=2-1/3
\(\dfrac{3}{2}X-0,2=\dfrac{3}{5}\)
\(\dfrac{1}{3}+x=\dfrac{3}{4}\)
\(1\dfrac{1}{2}x-\dfrac{2}{5}=\dfrac{1}{4}\)
\(\dfrac{11}{8}-\dfrac{3}{8}.x=\dfrac{1}{8}\)
