i means (1,0) ???
OpenStudy (anonymous):
move everything over to left side... -3 - x + yi - 6i = 0 then -3 - x = 0 and (y - 6)i = 0 solve
OpenStudy (anonymous):
-3 + yi = x + 6i comparing real and imaginary numbers from both sides we find x=-3 and yi=6i i.e. y=6i/i=6 thus x= -3 and y=6 make the equation true
