Discussion Overview

The discussion revolves around solving two equations presented in the thread title, specifically 8x-4=9x+6 and -x=10. However, there is confusion regarding the relevance of the equations to the content of the initial post, which appears to address a different problem involving complex numbers.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant points out a discrepancy between the thread title and the content of the post, asking for clarification on which problem is being addressed and what attempts have been made.
  • Another participant suggests that imaginary and real parts can be treated separately in complex number addition, indicating a willingness to assist further if the original poster shares where they are stuck.
  • A participant attempts to solve a complex number problem, showing the steps taken to combine two complex numbers and expressing the result in the form a+bi.
  • There is a repetition of the complex number solution, emphasizing the method used to separate real and imaginary components.
  • A later reply humorously notes that the original poster likely intended to express the sum of the complex numbers in the standard form, reinforcing the focus on complex numbers rather than the equations in the title.

Areas of Agreement / Disagreement

Participants generally agree that there is confusion regarding the problem being discussed, with multiple competing views on how to proceed. The discussion remains unresolved as to which problem should be addressed.

Contextual Notes

The initial equations presented in the title do not align with the content of the posts, leading to ambiguity about the intended problem. There are also unresolved assumptions regarding the original poster's understanding and attempts at solving the equations.

Your thread title and post content show two different problems...which one is correct? And what have you tried? I ask because we can better give you help if we see what you have tried as this gives us an indication of where you're stuck or may be going wrong.
 
You can treat imaginary parts and real parts separately - they add in the same way "regular" numbers do. We'll be able to help you more if we know where you're stuck :)
 
Well the title of the thread is different from the post of the thread, it was previous post which I was solved few minutes ago.
But I will solve your problem.
Problem---> (-9+3i)+(4+5i)=?
-9+3i+4+5i=?
Transfer the imaginary no. to one side and real no. to other side
3i+5i=9-4
8i=5
i=5/8
I think my solution will help you.

I believe the OP was supposed to express the sum of the two given complex numbers in the form $a+bi$ where:

$$i\equiv\sqrt{-1}$$

:D
