Answer 1

[Dương Lam Hàng]

Ta có: \(1-\left(\frac{49}{9}+x-\frac{133}{18}\right):\frac{11}{2}=\frac{4}{9}\)

\(\Rightarrow\left(\frac{49}{9}+x-\frac{133}{18}\right):\frac{11}{2}=1-\frac{4}{9}=\frac{5}{9}\)

\(\frac{49}{8}+x-\frac{133}{19}=\frac{5}{9}.\frac{11}{2}=\frac{55}{18}\)

\(\frac{49}{8}+x=\frac{55}{18}+\frac{133}{19}=\frac{181}{18}\)

\(\Rightarrow x=\frac{181}{18}-\frac{49}{8}=\frac{283}{72}\)

Vậy \(x=\frac{283}{72}\)

Answer 2

[Huỳnh Thị Minh Huyền]

1 - ( 49/9 + x -133/18 ):11/2 = 4/9

1 - ( 49/9 + x - 133/18 ) = 4/9 . 11/2

1 - ( 49/9 + x - 133/18 ) = 22/9

49/9 + x - 133/18 = 1 - 22/9

49/9 + x - 133/18 = - 13/9

49/9 + x = -13/9 - 133/18

49/9 + x = -53/6

x = -53/6 -49/9

x = -257/18
