I 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?

i dont know how to write a line above the letter for this

so for this question, there would be a line above the z and the 7+3i

So why don't you just write z  2z = 2 + 4i + (7  3i)? Is that what the question says?

no, there is no line above the z+2z, just the z

\(\bar{z} + 2z = 2 + 4i + \overline{7+3i} = 2 + 4i + 7  3i = 9 + i\)

answer is 3+i though...you seem to be on the right track though

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

Please read the problem statement. "solve for z, and give your answer in the form a + bi" z is a Complex Number

You 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?

i understand why you get this but why did you do this

you equate this to 9+i?

That is it! \(3a + bi = 9 + i\)
