Để (2x-3).(3/4x+1)=0
<=> 2x-3 = 0 => 2x = 0+3 => 2x = 3 => x = 3:2 => x = 3/2
3/4x+1 = 0 => 3/4x = 0-1 => 3/4x = -1 => x = -1 : 3/4 => x = -4/3
Vậy x = 3/2 và -4/3
|2 + 3x| = |4x - 3|
|3/2x + 1/2| = |4x - 1|
|5/4x - 7/2| - |5/8x + 3/5| = 0
|7/5x + 3/2| - |4/3 - 1/4| = 0
a) (5x-1) . ( 2x-1/3)=0
b) ( -0,6x-1/2) .3/4-(-1)=1/3
c) ( 4x-9) ( 2,5+-7/3x)=0
d) 1/4x-1+1/3.(5/2x-6)-( 3/8x +)=4,5
các bn giúp mk vs
2x-3=x+1/2
4x-(x+1/2)=2x-(1/2-5)
2/3-1/3(x-2/3)-1/2(2x+1)=5
(x+1/2).(x-3/4)=0
(2x-1).(3x+1/5)=0
4x^2 -2x=0
ai giúp mik, cho 10 like VIỆT NAM nói là làm
(2x-3)(3/4x+1)=0
a,/1-4x/=2x-3
b,/2x/+3=5-2x
c,/3x-1/=6
d,x(x+2/3)=0
x-(x-1/2)=0
(4x-1)(2x-2)-(2x-3)(2x-1)=0
tìm x
tìm x:
a) |4 - x| + 2x = 3
b) |x - 7| + 2x + 5 = 6
c) 3x - |2x + 1| = 2
d) |x + 2| - x = 2
e) |x - 3| = 21
f) |2x + 3| - |x - 3| = 0
g) |x + 1/8| + |x + 2/8| + |x + 5/8| = 4x
h) |x - 2| - |2x + 3| - x = -2
i) |2x - 3| - x = |2 - x|
k) 2. |x - 3| - |4x -1 = 0
A) 4x.|x+3|-2x(x-5)=0
B) 7x.(3-2x)-4x(x+1)=0
CÁC BẠN ƠI GIÚP MK GẤP GẤP NHA
(2x+1).(4x-3)=0
