Giải phương trình sau \(\frac{50}{x-49}+\frac{49}{x-50}=\frac{x-49}{50}+\frac{x-50}{49}\):
Giải phương trình
\(\frac{x-49}{50}\)+\(\frac{x+50}{49}\)=\(\frac{49}{x-50}\)+\(\frac{50}{x-49}\)
\(\frac{x-49}{50}+\frac{x-50}{49}=\frac{50}{x-49}+\frac{49}{x-50}\)
giúp mình!! please
Giải phương trình:
a,\(\frac{5-x}{4x^2-8x}+\frac{7}{8x}=\frac{x-1}{2x\left(x-2\right)}+\frac{1}{8x-16}\)
b,\(\frac{x-49}{50}+\frac{x-50}{49}=\frac{49}{x-50}+\frac{50}{x-49}\)
c,\(\frac{1}{x\left(x+1\right)}+\frac{1}{\left(x+1\right)\left(x+2\right)}+\frac{1}{\left(x+2\right)\left(x+3\right)}=\frac{1}{x+3}\)
chỉ mik cách giải pt này ko đọc lun kq đâu \(\frac{x-49}{50}+\frac{x-50}{49}=\frac{49}{50-x}+\frac{50}{49-x}\)
a,\(\frac{x+14}{86}+\frac{x+15}{85}+\frac{x+16}{84}+\frac{x+17}{83}+\frac{x+116}{4}=0\)\(=0\)
b,\(\frac{x-49}{50}+\frac{x-50}{49}=\frac{49}{50-x}+\frac{50}{49-x}\)

1) giải phương trình:
a) \(\left(2x+3\right)\left(\frac{3x+8}{2-7x}+1\right)=\left(x+5\right)\left(\frac{3x+8}{2-7x}+1\right)\)
b) \(\frac{7x+10}{x+1}\left(x^2-x-2\right)-\frac{7x+10}{x+1}\left(2x^2-3x-5\right)=0\)
c) \(\frac{2x+5}{x+3}+1=\frac{4}{x^2+2x-3}-\frac{3x-1}{1-x}\)
d) \(\frac{13}{2x^2+x-21}+\frac{1}{2x+7}+\frac{6}{9-x^2}=0\)
e) \(\frac{x-49}{50}+\frac{x-50}{49}=\frac{49}{x-50}+\frac{50}{x-49}\)
f) \(\frac{1+\frac{x}{x+3}}{1-\frac{x}{x+3}}=3\)
Giải các phương trình sau:
9) x-49/ 50 + x-50/ 49 = 49/ x-50 + 50/ x-49
8) 99-x/101 + 97-x/103 + 95-x/105 + 93-x/107 = 4
10) x+14/86 + x+15/85 + x+16/84 + x+17/83 + x+116/4 = 0
Giải phương trình sau
(x- 49)/50 +(x- 50)/49=49/(x- 50)+50/(x-49)
