3) 8,75 x X + 1,25x X + 26,3                                    4) 5\(\frac{4}{5}\)+ X - 7\(\frac{7}{18}\)=15\(\frac{3}{4}\)

Answer 1

[Hoàng Thái Ngọc]

1,x=\(\frac{47}{6}\)

2,x=\(\frac{11}{6}\)

4, x=\(\frac{3121}{180}\)

câu 3 cho đề sai rồi kìa 

chúc bạn học giỏi

Answer 2

[TRỊNH ANH TUẤN]

1) \(x-\frac{29}{6}=\frac{13}{6}+\frac{5}{6}\)

   \(x-\frac{29}{6}=3\)

  \(x=3+\frac{29}{6}\)

  \(x=\frac{47}{6}\)

2, X x ( 8,75 + 1,25 ) = 26,3

   X  x   10                = 26,3

   X                          = 26,3 : 10

  X                           = 2,63

3 , \(x+\frac{2}{3}=\frac{5}{2}\)

   \(x=\frac{5}{2}-\frac{2}{3}\)

  \(x=\frac{11}{6}\)

4,\(\frac{29}{5}+x-\frac{133}{18}=\frac{63}{4}\)

  \(\frac{29}{5}+x=\frac{63}{4}+\frac{133}{18}\)

  \(\frac{29}{5}+x=\frac{833}{36}\)

\(x=\frac{833}{36}-\frac{29}{5}=\frac{3121}{180}\)
