Question

Determine a value for b so that (3+2i)−(4+bi)=−2+2i.

Answer 1

3-4 is not -2 so i cant see this working out

Answer 2

b can be another complex number

Answer 3

and how you got 2i-bi=2i i don't understand as well

Answer 4

a complex number (a+bi) is defined for (a,b) in Real, isnt it?

Answer 5

otherwise the questions needs to be clarified

Answer 6

i donno, but you assume b=x+iy, it is solvable

Answer 7

if thats the case, then its just algebra ... isolate b

Answer 8

ye, but i agree, probably mistake in the question

Answer 9

if we assume to let 'b' amount to anything that makes it work, then we need not restrict ourselves to the reals, or the complex ... and the question becomes rather moot.
