Ta thấy: \(\begin{cases}\left|y-1,5\right|\ge0\\\left(x-1\right)^2\ge0\end{cases}\)
\(\Rightarrow\left|y-1,5\right|+\left(x-1\right)^2\ge0\)
Mà \(\left|y-1,5\right|+\left(x-1\right)^2=0\)
\(\Rightarrow\begin{cases}\left|y-1,5\right|=0\\\left(x-1\right)^2=0\end{cases}\)\(\Rightarrow\begin{cases}y-1,5=0\\x-1=0\end{cases}\)\(\Rightarrow\begin{cases}y=1,5\\x=1\end{cases}\)
