Question

(2x+3yi)+(y+XI)=6+13i

Answer 1

$2x+3yi+y+xi=6+13i\\\\ \left \{ {{2x+y=6} \atop {x+3y=13}} \right.$

Montando um sistema, temos que:

$\left \{ {{x+3y=13}*(-2) \atop {2x+y=6}} \right.\\\\ \left \{ {{x+3y=13}\atop {2x-2x+y-6y=6-26}} \right.\\\\ -5y=-20\\\\ \boxed{y=4}$

$x+3y=13\\\\ x+3*4=13\\\\ x+12=13\\\\ \boxed{x=1}$
