Question

\(\frac{x-1}{2005}=\frac{3-y}{2006}vax-y=4009\)

Answer 1

Áp dụng TC DTSBN ta có :

\(\frac{x-1}{2005}=\frac{3-y}{2006}=\frac{x-1+3-y}{2005+2006}=\frac{x-y+2}{4011}=\frac{4009+2}{4011}=1\)

\(\Rightarrow\frac{x-1}{2005}=1\Rightarrow x-1=2005\Rightarrow x=2006\)

\(\Rightarrow\frac{3-y}{2006}=1\Rightarrow3-y=2006\Rightarrow y=-2003\)

Vậy x = 2006; y = - 2003
