solve for z, and give your answer in the form a + bi
(conj)z+2z = 2+4i+conj(7+3i)
**conj refers to conjugate of a complex number
(a line on top of it)

Best ResponseYou've already chosen the best response.0I don't understand the notation of the equation. Why did you put (conj)? Does it mean take the conjugate of the term that follows it? Or multiply that term by its conjugate? Or what?

Best ResponseYou've already chosen the best response.1so for this question, there would be a line above the z and the 7+3i

Best ResponseYou've already chosen the best response.0So why don't you just write z  2z = 2 + 4i + (7  3i)? Is that what the question says?

Best ResponseYou've already chosen the best response.1no, there is no line above the z+2z, just the z

Best ResponseYou've already chosen the best response.2It's not my problem statement. You need to be on the right track. Where shall we go from here? \(\bar{z} + 2z = 9 + i\)

Best ResponseYou've already chosen the best response.1i dont know what the z part is. that is the problem

Best ResponseYou've already chosen the best response.2Please read the problem statement. "solve for z, and give your answer in the form a + bi" z is a Complex Number

Best ResponseYou've already chosen the best response.2You tried what? \(\bar{z} + 2z = a  bi + 2(a + bi) = a  bi + 2a + 2bi = (a + 2a) + (2bb)i\) Do yuo see where this is going?

Best ResponseYou've already chosen the best response.1i understand why you get this but why did you do this

Best ResponseYou've already chosen the best response.2That is it! \(3a + bi = 9 + i\)
