|2x - 1| = |2x + 3|
=> 2x - 1 = 2x + 3 => 0x = 4 (vô nghiệm)
hoặc 2x - 1 = -2x - 3 => 4x = -2 => x = -1/2
Vậy x = -1/2

Tim x biet
x-4/3=x+2/-2
2x-1/x-3=2x+3/x-1
Tim x, biet:
a.(3-x)+(2x+7)=2x
b. \(\dfrac{x+1}{2}=\dfrac{1}{3}\)
GIUP MK VS
tim x
2 - /3/2x - /1/4/=/-5/4
Tim x :
\(\frac{13}{x-1}+\frac{5}{2x-2}-\frac{6}{3x-3}=3\)
Tim nghiem
c.)C(x)=\(\dfrac{1}{2}-7x+2x^3-2.\left(x+2^3+x^3\right)\)
Tim x thuoc z de ps sau co gia tri la so nguyen
D = 2x - 3 / x - 1
tim x biet |2x+3|-2|4-x|=5
tim GTLN: D=-3-/2x+4/
tìm GTNN:A=3*/1-2x/-5
Bai 1 :cho A(x)=2x^2-8x
tim nghiem A(x)
b,tim B(x) biet B(x)=A(x)-3x+2x^2
c,tim ngiem B(x)
Bai2
Cho ham so y=f(x)=x+1
cac diem sau diem nao thuoc do thi ham so :A(0;1).B(1/2;-1). C(-1/2;0)
