Question

solve graphicall y=2+1 x=2y_5

Answer 1

$y = 2x + 1 \\ 2x - y + 1 = 0..........(1) \\ x = 2y - 5 \\ x - 2y + 5 = 0 ...........(2)\\ multiply \: with \: 2 \\ 2x - 4y + 10 = 0 .........(3)\\ equation(3) - \: equation (1) \\ y = 3 \\ put \: value \: of \: y \: in \: (1) \\ x = 1 \\ point \: of \: intersection \: is \: (1.3)$
