Question

x+2y=6 2x=8-4y how to solve and is it consistent or inconsistent

Answer 1

$\left \{ {{x+2y=6} \atop {2x=8-4y}} \right. \\\\ \left \{ {{x+2y=6|*(-2)} \atop {2x+4y=8}} \right.\\\\ \left \{ {{-2x+-4y=-12} \atop {2x+4y=8}} \right.\\+----\\ 0 \neq -4\\\\ There\ are\ no\ solutions\\ It\ is\ inconsistent.$
