Question from Rasanga, a student: Use the row echelon form of the augmented matrix to solve the following linear system. |
Rasanga,
The augmented matrix is already in row echelon form
From this, or the equations you have, you can read off the solution
x5 = 1
x3 = 7 - 6x4
x1 = 6 - 2x2 - x4
There are in fact infinitely many solutions since x2 and x4 can be given any values and the x1, x3 and x5 generated by the expressions above.
