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
\(\frac{201-X}{99}+\frac{203-X}{97}\)bằng \(\frac{205-X}{95}+3\)
Giari phương trình:
b)(x+1)(2x-3)=(2x-3)(x+5)
c)x-2/x+2 - 3/x-2 = 2(x-11)/x^2 - 4
d)201 - x/99 + 203-x/97= 205-x/95 - 1
Giải hộ mik pt này nha ^.^ :
\(\frac{201-x}{99}\)+\(\frac{203-x}{97}\)+\(\frac{205-x}{95}\)+ 3 = 0
Giải PT:
\(\frac{201-x}{99}\) + \(\frac{203-x}{97}\)= \(\frac{205-x}{95}\)+ 3 = 0
Giải phương trình sau:
\(\frac{201-x}{99}+\frac{203-x}{97}=\frac{205-x}{95}+3\)
giai phuong trinh
1.
(x+1)/2004+(x+2)/2003=(x+3)/2002+(x+4)/2001
2.(201-x)/99+(203-x)/97=(205-x)/95+3
