Giải phương trình:
a) \(\dfrac{x^2-x-6}{x-3}=0\)
b) \(\dfrac{x+5}{3x-6}-\dfrac{1}{2}=\dfrac{2x-3}{2x-4}\)
c) \(\dfrac{12}{1-9x^2}=\dfrac{1-3x}{1+3x}-\dfrac{1+3x}{1-3x}\)
d) \(\dfrac{x+5}{x-1}=\dfrac{x+1}{x-3}-\dfrac{8}{x^2-4x+3}\)
e) \(\dfrac{x+1}{x-2}-\dfrac{5}{x+2}=\dfrac{12}{x^2-4}+1\)Thể loại truyện
Giải phương trình
\(\dfrac{4+x}{3}-\dfrac{x-\dfrac{x-1}{2}}{2}+\dfrac{x-3}{4}=\dfrac{6-2x}{2}\)
1, \(\dfrac{\left(2x-3\right)\cdot\left(2x+3\right)}{8}=\dfrac{\left(x-4\right)^2}{6}+\dfrac{\left(x-2\right)^2}{3}\)
2, \(x+2-\dfrac{2x-\dfrac{2x-5}{6}}{15}=\dfrac{7x-\dfrac{x-3}{2}}{5}\)
3, \(1-\dfrac{x-\dfrac{1+x}{3}}{3}=\dfrac{x}{2}-\dfrac{2x-\dfrac{10-7}{3}}{2}\)
4, \(\dfrac{x+1}{99}+\dfrac{x+3}{97}+\dfrac{x+5}{95}=\dfrac{x+7}{93}+\dfrac{9+x}{91}+\dfrac{x+11}{89}\)
Giải phương trình: \(\left(\dfrac{x+1}{x+2}\right)^2+\dfrac{x+1}{x-4}-3.\left(\dfrac{2x-4}{x-4}\right)^2=0\)
Đề bài: Giải các phương trình
a) \(\dfrac{1}{x}\) - \(\dfrac{2}{x+1}\) = \(\dfrac{3}{x^2+x}\)
b) \(\dfrac{x+2}{x-2}\) - \(\dfrac{1}{x}\) = \(\dfrac{2}{x\left(x-2\right)}\)
c) \(\dfrac{x-2}{x+2}\) - \(\dfrac{3}{x-2}\) = \(\dfrac{2\left(x-11\right)}{x^2-4}\)
giải phương trình:
a) \(\left(\dfrac{x}{2}+1\right)^3-\dfrac{x^3}{2}-4=0\)
b) \(\dfrac{3-x}{2007}+1=\dfrac{2-x}{2008}-\dfrac{x}{2009}\)
bài 1 : Giải cac phuong trinh sau
a, \(\dfrac{x-3}{5}=6-\dfrac{1-2x}{3}\)
b, \(\dfrac{3x-2}{6}-5=\dfrac{3-2\left(x+7\right)}{4}\)
c, \(2\left(x+\dfrac{3}{5}\right)=5-\left(\dfrac{13}{5}+x\right)\)
d, \(\dfrac{5\left(x-1\right)+2}{6}-\dfrac{7x-1}{4}=\dfrac{2\left(2x+1\right)}{7}-5\)
e, \(\dfrac{x-1}{2}+\dfrac{x-1}{4}=1-\dfrac{2\left(x-1\right)}{3}\)
g, \(\dfrac{2-x}{2001}-1=\dfrac{1-x}{2002}-\dfrac{x}{2003}\)
