3.(2x-1)-x.(1-2x)=0
=>3.(2x-1)=x.(1-2x)
=>3.(2x-1)=x.(-1.(-1)+(-1).2x)
=>3.(2x-1)=x.(-1).(-1+2x)
=>3.(2x-1)=-x.(2x-1)
=>3=-x
=>x=-3
Tìm x, biết
a)(2x-1)^5-(2x-1)^8=0
b)(2x+1). (2x-3)<0
c)(x-1). (2x+3)>0
tìm x thoả mãn
(2x-1)(2x-5)<0
(3-2x)(x+2)>0
(3x+1)(5-2x)>0
mình đang rất cần
|x-3| + |y-2x | =0 |x| + 3|2x -x ² | =0 |5x ² -5 | + 4|y-7 | =0 ||x +1 | + |y-5 |=0 |x ² -1| + |y-1| =0 |x-1 | +|x ²-x |=0
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
Bài 3: Tìm x biết:
a. \(2x+10=0\)
b. \(-2x+5=0\)
c. \(4-x=0\)
d. \(2x+1=0\)
e. \(x^2+2=0\)
f. \(2x+x=0\)
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
-5x(x+1/5)-1/2x(x-2/3)=3/2
(x+1)x(x-3)=0
(3x-1)x(-1/2x+5)=0
Tìm x:2x(x-4)-x(2x+3)+22=0
(2x+3)(3x+2)+2(1-3x)(x+1/2)= 1
C=(2x-2)(3x+3)<0
D=(3x+1)(2x-2)>0
E=(1-2x)(2+5x)<0
G=2x-1/3x-1>0
H=-2x+1/x-2<0
a, | 5x - 1 | - x = 2x + 3
b, |2x + 1 | + | x - 3 | + | 2x + 3 | = x - 5
c, 2 xy - 3y + 2x + 10 = 0
