a: \(\Leftrightarrow x+2016=0\)
hay x=-2016
b: \(\Leftrightarrow x-100=0\)
hay x=100
\(\dfrac{3}{x-2}+\dfrac{x-1}{x+2}=\dfrac{9}{x^2-4}\)
giải chi tiết giúp e ạ
\(\dfrac{x}{2012}\) +\(\dfrac{x+1}{2013}\)+\(\dfrac{x+2}{2014}\)+\(\dfrac{x+3}{2015}\)+\(\dfrac{x+4}{2016}\)=5
1) GIẢI phương trình :
a) 2x-6=0
b) x2-4x=0
c)\(\dfrac{x+2}{x-3}\)-\(\dfrac{3}{x}\)=\(\dfrac{x+9}{x^2-3x}\)
d) \(\dfrac{x-1}{2}\)-\(\dfrac{x-2}{3}\)=x-\(\dfrac{x-3}{4}\)

Giải phương trình sau:
\(\dfrac{x-1}{2013}+\dfrac{x-2}{2012}+\dfrac{x-3}{2011}=\dfrac{x-4}{2010}+\dfrac{x-5}{2009}+\dfrac{x-6}{2008}\)
Giải phương trình sau:
\(\dfrac{x-1}{2013}+\dfrac{x-2}{2012}+\dfrac{x-3}{2011}=\dfrac{x-4}{2010}+\dfrac{x-5}{2009}+\dfrac{x-6}{2008}\)
Giải PT sau:
\(\dfrac{x+19}{3}+\dfrac{x+13}{5}=\dfrac{x+7}{7}+\dfrac{x+1}{9}\)
Giải chi tiết giúp mình nheee :>
bài 1: giải phương trình
a, \(\dfrac{-3}{x^2-9}\)+ \(\dfrac{5}{3-x}\)=\(\dfrac{2}{x+3}\)
b, \(\left|x+5\right|\) = 2x-1
c, \(^{x^4}\)- \(^{x^3}\)+2\(^{x^2}\)-x + 1 = 0
Bài 1 giải phương trình:
a) (4x2+4x+1)-x2=0
b) x2-2x+1=4
c) x2-5x+6=0
Bài 2: giải phương trình
a) \(\dfrac{2x-5}{x+5}\)= 3
b) \(\dfrac{5}{3x+2}\)= 2x-1
c) \(\dfrac{x^2-6}{x}\)= x+\(\dfrac{3}{2}\)
d) \(\dfrac{1}{x-2}\)+3= \(\dfrac{x-3}{2-x}\)
e) \(\dfrac{3x-2}{x+7}\)=\(\dfrac{6x+1}{2x-3}\)
f) \(\dfrac{x-2}{x+2}\) - \(\dfrac{3}{x-2}\)=\(\dfrac{2\left(x-11\right)}{x^2-4}\)
