1/ \(\dfrac{x-4}{3}+2x=\dfrac{4x-2}{6}\)
2/ \(\dfrac{5x-2}{5}-2=\dfrac{1-2x}{3}\)
3/ \(\dfrac{x-2}{2}-\dfrac{2}{3}=x-1\)
4/ \(\dfrac{2x-1}{3}+\dfrac{3x-2}{4}=\dfrac{4x-3}{5}\)
5/ \(\dfrac{x-3}{9}-\dfrac{x+2}{6}=\dfrac{x+4}{18}-\dfrac{1}{2}\)
P= \(\dfrac{2x-9}{x^2-5x+6}-\dfrac{x+3}{x-2}-\dfrac{2x+1}{3-x}\)(x≠2;x≠3)
Giải phương trình:
a) \(\dfrac{5x}{2x+2}+1=\dfrac{6}{x+1}\)
b) \(-\dfrac{48}{x^2-9}=\dfrac{x-3}{x+3}-\dfrac{x+3}{x-3}\)
\(\dfrac{2x^2+5x-1}{x-3}\) : \(\dfrac{x^3-2x+5}{x-3}\): \(\dfrac{2x^2+5x-1}{2}\)
