Question

Tìm x,y biết: \(\frac{4}{x}=\frac{-y}{6}=0,5\)

 

Answer 1

\(\frac{4}{x}=0,5\Rightarrow x=4:0,5=8\)

\(-\frac{y}{6}=\frac{y}{-6}=0,5\Rightarrow y=0,5.\left(-6\right)=-12\)

Answer 2

\(\frac{4}{x}=0,5\Rightarrow x=4.0,5=8;-\frac{y}{6}=\frac{y}{-6}=0,5\Rightarrow y=0,5.\left(-6\right)=-3\)
