\(\overline{9abcd}-\overline{abcd7}=90000+\overline{abcd}-\overline{abcd0}-7=51104\)

                                          \(89993+\overline{abcd}\left(1-10\right)=51104\)

                                          \(89993-51104=-\overline{abcd}\left(-9\right)\)

                                           \(38889=9\overline{abcd}\)

                                            \(\overline{abcd}=4321\)

  Vậy \(\overline{abcd}=4321\)

Theo đề bài , ta có :

10abcd +7 + 864 = 70000 +abcd 

9abcd = 70000-864-7

9abcd = 69129

abcd= 69129 / 9

        =7681

vậy abcd =7681

Ta có abcd7 +864 =7abcd 

     =>abcd*10 +7 +864= 70000 +abcd

     =>9*abcd=69129

     =>abcd=7681
