T ìm X

125,5 : 5 + X = 37,86                                                     34,27 : 0,1 – X = 89,02

Answer 1

\(125,5 : 5 + x = 37,86 \)

\(25,1 + x = 37,86 \)

\( x = 37,86 - 25,1 \)

\(x=12,76\)

\(----------\)

\( 34,27 : 0,1 –x = 89,02\)

\(342,7-x = 89,02\)

\(x = 342,7-89,02\)

\(x=253,68\)

Answer 2

`125,5 : 5 + x = 37,86`

`25,1 + x = 37,86`

`x=37,86 - 25,1`

`x=12,76`

________________

`34,27 : 0,1 - x = 89,02`

`34,27 xx 10 - x = 89,02`

`342,7 - x = 89,02`

`x = 342,7 - 89,02`

`x=253,68`

Answer 3

125,5 : 5 + X = 37,86 

     25,1   + X = 37,86

                  X = 37,86 - 25,1

                  X = 12,76

Vậy X = 12,76

34,27 : 0,1 - X = 89,02

       342,7 -  X = 89,02

                    X = 342,7 - 89,02 

                    X = 253,68

Vậy X = 253,68
