Question

19 +x/91=3/13

 

Answer 1

\(19+\frac{x}{91}=\frac{3}{13}\)

\(=>\frac{x}{91}=\frac{3}{13}-19=\frac{3}{13}-\frac{247}{13}=\frac{-244}{13}\)

\(=>\frac{x}{91}=\frac{-1708}{91}\)

\(=>x=-1708\)

Answer 2

\(19+\frac{x}{91}=\frac{3}{13}\)

<=>\(\frac{x}{91}=\frac{3}{13}-19\)

<=>\(\frac{x}{91}=\frac{-244}{13}\)

<=>\(x=\frac{\left(-244\right).91}{13}\)

,<=>\(x=-1708\)

Answer 3

\(19+\frac{x}{91}=\frac{3}{13}\)

\(\frac{x}{91}=-\frac{244}{13}\)

\(x=-1708\)

Answer 4

Trả lời:

\(19+\frac{x}{91}=\frac{3}{13}\)

\(\Leftrightarrow\frac{x}{91}=\frac{3}{13}-19\)

\(\Leftrightarrow\frac{x}{91}=\frac{3}{13}-\frac{247}{13}\)

\(\Leftrightarrow\frac{x}{91}=\frac{-244}{13}\)

\(\Leftrightarrow x=\frac{-244}{13}.91\)

\(\Leftrightarrow x=-1708\)

Vậy\(x=-1708\)

Hok tốt!
