Question

Find the general solution of the system whose augmented matrix is given below. [Start 3 By 4 Matrix 1st Row 1st Column 3 2nd Column negative 7 3rd Column 5 4st Column 0 2nd Row 1st Column 12 2nd Column negative 28 3rd Column 20 4st Column 0 3rd Row 1st Column 9 2nd Column negative 21 3rd Column 15 4st Column 0 EndMatrix ]

Answer 1

From what was given in the question, I have tried to reduce the matrix to echelon form and here is the equation I got ; 3x - 7y + 5z = 0

Explanation:

From the analysis, the matrix may not have a general solution i.e values of x , y and z may all be zero. But I have tried to analyze the matrix by bringing it from the question given. I have also tried to reduce to echelon form.
