Best ResponseYou've already chosen the best response.0In equations like this you can always separate real and imaginary numbers into separate equations. So, hypothetically if you had x+yi = 4  3i you could separate the equation to x=4 and yi= 3i, so x=4 and y= 3 Now back to your question: First you multiply things out (this isn't that important for the above question, but could be if you had to keep track of multiplying i's together i.e. x + (y+zi)*(i+3) = 8. I won't solve it, but you would have to "FOIL" that last part.) so... back to your question again. multiplying stuff out... a  1 + b*i +3*i = 5 + 8*i separate into separate equations for real and imaginary (as shown at top) a  1 = 5 b*i + 3*i = 8*i now solve using basic algebra to get... a = 6 b*i = 5*i, therefore b=5
