Step-by-step explanation:
Start replacing!
Now two complex numbers are equal if both the real and imaginary parts are equal, which gives you the system of equation![\left \{x+4y=-3} \atop {4x+y=18} \right.](/tpl/images/0231/4235/88467.png)
Pick any method to solve it and you'll get![x=5, y= -2](/tpl/images/0231/4235/de1d6.png)
