giải phương trình trên
Giải phương trình sau
\(\frac{x-45}{55}+\frac{x-47}{53}=\frac{x-55}{45}+\frac{x-53}{47}\)
giải phương trình sau 
\(\frac{x-45}{55}+\frac{x-47}{53}=\frac{x-55}{45}+\frac{x-53}{47}\)
Giải phương trình :
a, x-45/55 +x-47/53 =x-55/45 + x-53,47
b, x^2-10x-29/1971 +x^2-10x-27/1973 = x^2-10x-1971/29 + x^2-10x-1973/27
c, 2-x/2002-1= 1-x/2003 -x/2004
Các bạn giúp mik vs nhé !
a) \(\dfrac{x-45}{55}+\dfrac{x-47}{53}=\dfrac{x-55}{45}+\dfrac{x-53}{47}\)
b)\(\dfrac{x+1}{2004}+\dfrac{x+2}{2003}=\dfrac{x+3}{2002}+\dfrac{x+4}{2001}\)
giải phương trình: (59-x/41) + (57-x/43) + (55-x/45) + (53-x/47) + (51-x/49) = -5
\(\dfrac{59-x}{41}+\dfrac{57-x}{43}+\dfrac{55-x}{45}+\dfrac{53-x}{47}+\dfrac{51-x}{49}=-5\)
giải phương trình trên
(x-24)/55+(x-26)/53=(x-34)/45+(x-32)/47=0
Giải các phương trình sau:
a)\(\frac{x+1}{2004}+\frac{x+2}{2003}=\frac{x+3}{2002}+\frac{x+4}{2001}\)
b) \(\frac{201-x}{99}+\frac{203-x}{27}=\frac{205-x}{95}+3\)
c) \(\frac{x-45}{55}+\frac{x-47}{53}=\frac{x-55}{45}+\frac{x-53}{47}\)
