SUMMARY

The discussion focuses on determining the values of h and k for which the system of equations has no solution. The equations presented are: 5x + 3y + 6z = -5, -6x - 7y - 4z = 9, and -17x - 17y + hz = k. The key takeaway is that to find the conditions for no solution, one can express x, y, and z in terms of h and k without using matrix manipulation, which is not yet covered in the class. This approach simplifies the problem to identifying specific values of h and k that lead to contradictions in the equations.

PREREQUISITES
  • Understanding of linear equations and systems of equations
  • Basic algebraic manipulation skills
  • Familiarity with variables and parameters in equations

Homework Statement



Determine all values of h and k for which the system has no solution:

5x + 3y + 6z = -5
-6x - 7y - 4z = 9
-17x - 17y + hz = k

k =! ?
h = ?

The Attempt at a Solution



I googled the question and apparently most people solve this with a matrix, but we haven't gotten far enough in the class where we manipulate matrices or anything of the sort. Nor have we done an example of this in class. I am a bit clueless as to both what the question is asking and of course how to go about solving it.

That's a system of equations with 3 variables. So, if you don't want to solve it using matrices, simply solve for x, y, and z in terms of k and h, like you would solve a normal system of equations. At that point it will be easy to determine which values of h and k give no solution to the system.
