Question

27,9 - x = 25,79 +14,5

x - 4,55 = 16,72+25,497

Answer 1

1)

\(27,9 - x = 25,79 +14,5 \)

\(27,9-x=40,29\)

\(x=27,9-40,29\)

\(x=-12,39\)

2)

\( x - 4,55 = 16,72+25,497\)

\(x-4,55=42,217\)

\(x=42,217+4,55\)

\(x=46,767\)

Answer 2

a: =>27,9-x=40,29

=>x=-12.39

b: =>x-4,55=42,217

=>x=46,767

Answer 3

cụ thể là giải thích ạ

 

Answer 4

\(27,9-x=25,79+14,5\)

\(27,9-x=40,29\)

           \(x=27,9-40,29\)

           \(x=12,39\)

\(x-4,55=16,72+25,497\)

\(x-4,55=42,217\)

        \(x=42,217+4,55\)

        \(x=\text{46,767 }\)

Answer 5

27,9 - x = 25,79 + 14,5                     x - 4,55 = 16,72 + 25,497

27,9 - x =     40,29                            x - 4,55 =       42,217

          x =  40,29 - 27,9                               x = 42,217 + 4,55

          x =       12,39                                    x =         46,767
