Question

1/9=x+5/27

Giúp mik nha ai nhanh dc tick

Answer 1

<=> x=1/9-5/27=-2/27

Answer 2

\(\frac{1}{9}=\frac{x+5}{27}\)

=> 9(x + 5) = 27

=> 9x + 45 = 27

=> 9x = 27 - 45

=> 9x = -18

=> x = -18 : 9

=> x = -2

Answer 3

\(x=\frac{1}{9}-\frac{5}{27}=\frac{3}{27}-\frac{5}{27}=\frac{-2}{27}\)

Answer 4

\(\frac{1}{9}=x+\frac{5}{27}\)

\(x+\frac{5}{27}=\frac{1}{9}\)

\(x=\frac{1}{9}-\frac{5}{27}\)

\(x=\frac{1}{9}+\frac{-5}{27}\)

\(x=\frac{3}{27}+\frac{-5}{27}\)

\(x=\frac{-2}{27}\)

Vậy \(x=\frac{-2}{27}\)

Answer 5

ta có  \(\frac{x+5}{27}=\frac{1}{9}\)

\(\Rightarrow\)\(9.\left(x+5\right)=27\)

\(\Rightarrow\)\(9x+45=27\)

\(\Rightarrow\)\(9x=-18\)

\(\Rightarrow\)\(x=-2\)

vậy \(x=-2\)
