This is to help those that didn't understand the first guys explanation.

Answer 2

`\left \{ {{3x+2y=11\ \ \ \ \ \ \ } \atop add\ 2y} \right.\\\\ \left \{ {{3x+2y=11} \atop {x=4y+2y}} \right.\\\\substitution\ method\\\\ 3(4y+2y)+2y=11\\\\ 3*6y+2y=11\\\\ 18y+2y=11\\\\ 20y=11\ \ \ | divide\ by\ 20\\\\ y=(11)/(20)\\\\ x=6y=6* (11)/(20)=(66)/(20)=(33)/(10)\\\\`
