Review sheet #6
I'm also having trouble with #6. But I did it a different way. First I plugged in -4 for x and I got 16b + d=52, then I plugged in 2 + 5i for x and I got -80i - 21b + 20ib + d=148. Then I subtracted the first equation from the second to get rid of d. But after that I'm stuck.

I do not understand your way, but you can look at how Yu Chen did it on the comments of the other person who had trouble on #6
