Question

Tìm x , biết \(\frac{x+2}{327}+\frac{x+3}{326}+\frac{x+4}{325}+\frac{x+5}{324}+\frac{x+349}{5}=0\)

giúp mk vs

Answer 1

\(\frac{x+2}{327}\) +\(\frac{x+3}{326}\) +\(\frac{x+4}{325\ }+\frac{x+5}{324}+\frac{x+349}{5}=0\)

=> \(\left(\frac{x+2\ }{327}+1\right)+\frac{x+3}{326}+1+\frac{x+4}{325}+1+\frac{x+5}{324}\)+1+(\(\frac{x+349}{5}\) - 4) = 0

\(\frac{x+329}{327}\) + \(\frac{x+329}{326}+\frac{x+329}{325}\) + \(\frac{x+329}{324}\) +\(\frac{x+329\ }{5\ }\) = 0

(x+329).(1/327+1/326+1/325+1/324+1/5) = 0

=> x + 329 = 0

x = -329

có mấy chỗ mk quên đóng ngoặc bn sửa giúp mk nak
