Bài tập: Giải các phương trình sau:
1. \(\dfrac{5-x}{2003}-2=\dfrac{2-x}{2004}-\dfrac{5x}{2003}\)
2. \(\dfrac{3x+1}{2002}+1=\dfrac{2-3x}{2003}+\dfrac{4x+2}{2001}\)
Giải Phương trình :
\(a,\frac{1-x}{2013}=1+\frac{2-x}{2012}-\frac{x}{2014}\)
\(b,\frac{2-x}{2001}-1=\frac{1-x}{2002}-\frac{x}{2003}\)
\(c,\frac{x-a-b}{c}+\frac{x-b-c}{a}+\frac{x-a-c}{b}=3\)
a . \(\dfrac{2-x}{2001}-1=\dfrac{1-x}{2002}-\dfrac{x}{2003}\)
b . \(\dfrac{x-5}{100}+\dfrac{x-4}{101}=\dfrac{x-100}{5}+\dfrac{x-101}{4}\)
Mik cần gấp lắm . Thanks
