\(\dfrac{-7}{11}=\dfrac{x}{22}\Rightarrow\dfrac{-14}{22}=\dfrac{x}{22}\Rightarrow x=-14\)

\(\dfrac{-5}{11}=\dfrac{x}{33}\Rightarrow\dfrac{-15}{33}=\dfrac{x}{33}\Rightarrow x=-15\)

Answer 2

[Huynh Y T'ss]

\(\dfrac{-7}{11}\)=\(\dfrac{x}{22}\)\(\Rightarrow\)11x=-7.22\(\Rightarrow\)11x=-154\(\Rightarrow\)x=-154:11=-14

\(\dfrac{-5}{11}\)=\(\dfrac{x}{33}\)\(\Rightarrow\)11x=-5.33\(\Rightarrow\)11x=-165\(\Rightarrow\)x=-165:11=-15
