Question

Tìm x,y biết:

\(\left|x-2016\right|+\left|1008-\frac{1}{2}y\right|=0\)

Answer 1

\(\left|x-2016\right|+\left|1008-\frac{1}{2}y\right|=0\)

\(\Leftrightarrow\begin{cases}x-2016=0\\1008-\frac{1}{2}y=0\end{cases}\)\(\Leftrightarrow x=y=2016\)

Answer 2

\(\left|x-2016\right|+\left|1008-\frac{1}{2}y\right|=0\)

\(\Rightarrow\left|x-2016\right|=0\) và \(\left|1008-\frac{1}{2}y\right|=0\)

+) \(\left|x-2016\right|=0\Rightarrow x-2016=0\Rightarrow x=2016\)

+) \(\left|1008-\frac{1}{2}y\right|=0\)

\(\Rightarrow1008-\frac{1}{2}y=0\)

\(\Rightarrow\frac{1}{2}y=1008\)

\(\Rightarrow y=2016\)

Vậy \(x=y=2016\)
