Question

Tìm x,y thuộc Z biết : -( x + 3 )/27 = 11 / 1 - 2y = -121 / 33

 

Answer 1

\(\frac{-\left(x+3\right)}{27}=\frac{11}{1-2y}=-\frac{121}{33}\)\(\Rightarrow\frac{-\left(x+3\right)}{27}=\frac{-121}{33}\)\(\Rightarrow-\left(x+3\right)=\left(-121\right)\cdot27\div33=-99\Rightarrow x+3=99\Rightarrow x=96\)
                                                                     \(\frac{11}{1-2y}=\frac{-121}{33}\)\(\Rightarrow1-2y=33\cdot11\div\left(-121\right)=-3\Rightarrow2y=47\Rightarrow y=2\)
