[tex]\begin{cases}3x+2y=11 \\ 7x-y=3 \end{cases}\\ \\\begin{cases}3x+2*(7x-3)=11 \\ y=7x- 3 \end{cases}\\ \\\begin{cases}3x+14x-6=11 \\ y=7x- 3 \end{cases}\\ \\\begin{cases}17x =11+6 \\ y=7x- 3 \end{cases}[/tex]
[tex]\begin{cases}17x =17 \ \ /:17 \\ y=7x- 3 \end{cases}\\ \\\begin{cases}x=1\\ y=7*1- 3 \end{cases}\\ \\\begin{cases}x=1 \\ y=4\end{cases}[/tex]
