Find all Values of h for which a System of Linear Equations has No Solution

Click For Summary

Homework Help Overview

The problem involves a system of linear equations and seeks to determine the values of h for which the system has no solution. The context is within linear algebra, specifically focusing on the conditions for inconsistency in a system represented by an augmented matrix.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss transforming the system into an augmented matrix and identifying conditions for inconsistency. There is an exploration of the implications of specific values of h on the system's consistency.

Discussion Status

The discussion is ongoing, with participants sharing their attempts at manipulating the matrix and questioning the conditions under which the system becomes inconsistent. Some guidance has been offered regarding solving for h, but no consensus has been reached on the final values.

Contextual Notes

Participants are working with an augmented matrix derived from the original system of equations, and there is a focus on the specific expression involving h that determines inconsistency. The nature of the problem suggests that certain values of h may lead to a zero row in the augmented matrix, indicating no solution.

Try making that into an augmented matrix, then finding what values of h will make the system inconsistent. A hint: What makes an augmented matrix inconsistent?
 
okay i have gotten it down to

2 1 -3 1
0 7 -3 9
0 0 (-50+14h) 80

where do i go from here?

thanks
 
Well, you know from there that 14h-50 = 80. So solve that for h and you'll have the solutions such that it's consistent, at least I think so.
