Question

x:102=203(du1)

1234:x=9 (du 1)

Answer 1

x : 102 = 203 ( dư 1 )

=> x = 203 x 102 + 1

=> x = 20707

1234 : x = 9 ( dư 1 )

=> ( 1234 - 1 ) : x = 9

=> 1233 : x = 9

              x = 1233 : 9

               x = 137

Answer 2

x : 102 = 203 ( dư 1 )

=> x = 203 x 102 + 1

=> x = 20707

1234 : x = 9 ( dư 1 )

=> ( 1234 - 1 ) : x = 9

=> 1233 : x =9

x = 1233 : 9

 x = 137
