Answer 1

[Công chúa đáng yêu]

\(x-789=7896\times12\)

\(x-789=94752\)

              \(x=94752+789\)

              \(x=95541\)

\(x+7869=890+346146\)

\(x+7869=347036\)

                \(x=347036-7869\)

                \(x=339167\)

\(x\times231=462\)

              \(x=462:231\)

              \(x=2\)
