giải phương trình
\(\frac{x+5}{95}+\frac{x+3}{97}+\frac{x+1}{99}=\frac{x+15}{85}+\frac{x+20}{80}+\frac{x+25}{75}\)
Giải phương trình :
a) \(\frac{x+1}{99}+\frac{x+2}{98}+\frac{x+3}{97}=\frac{x+4}{96}+\frac{x+5}{95}+\frac{x+6}{94}\)
b) \(\frac{1}{3}.x-\frac{1}{2}=\left(\frac{3}{5}-4.x\right).\frac{15}{7}\)
Giải phương trình sau
\(\frac{x+1}{99}+\frac{x+2}{98}=\frac{x+3}{97}+\frac{x+4}{96}\)
\(\frac{109-x}{91}+\frac{107-x}{93}+\frac{105-x}{95}+\frac{103-x}{97}+4=0\)
Giải phương trình sau:
a) x+1/2004 + x+2/2003 = x+3/2002 + x+4/2001
b) 201-x/99 + 203-x/97 + 205-x/95 + 3 = 0
