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)

answer is 3+i (need to learn how to do it)

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

z = a + bi (conj)z = a - bi
anonymous
  • anonymous
it means to flip the sign of the imaginary part
anonymous
  • anonymous
So why don't you just write z - 2z = 2 + 4i + (7 - 3i)? Is that what the question says?
anonymous
  • anonymous
no, there is no line above the z+2z, just the z
anonymous
  • anonymous
Can you draw the question instead?

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

  • anonymous
answer is 3+i though...you seem to be on the right track though
anonymous
  • anonymous
no idea what the conjugate of a variable means...
anonymous
  • anonymous
unless you use fourier which i don't think you are

  • tkhunny
It's not my problem statement. You need to be on the right track. Where shall we go from here? \(\bar{z} + 2z = 9 + i\)
anonymous
  • anonymous
i dont know what the z part is. that is the problem
anonymous
  • anonymous
is z considered real or imaginary?
anonymous
  • anonymous
i tried it with both for hours
tkhunny
  • tkhunny
Please read the problem statement. "solve for z, and give your answer in the form a + bi" z is a Complex Number
anonymous
  • anonymous
oh
tkhunny
  • tkhunny
You tried what? \(\bar{z} + 2z = a - bi + 2(a + bi) = a - bi + 2a + 2bi = (a + 2a) + (2b-b)i\) Do yuo see where this is going?
anonymous
  • anonymous
no
anonymous
  • anonymous
i understand why you get this but why did you do this
anonymous
  • anonymous
you equate this to 9+i?
tkhunny
  • tkhunny
That is it! \(3a + bi = 9 + i\)
anonymous
  • anonymous
thanks
