To find the solutions for variables
in terms of
using the Reduced-Row Echelon Form (RREF) of the augmented matrix, you typically follow the resulting equations from the matrix.
For example, assume your RREF provides equations like:
From these equations, you can express
,
, and
in terms of
as follows:
Enter the coefficients accordingly while considering that
is a free variable.
Thus, if
for simplicity, your entries could be
and
, with the constant adjustments as appropriate.
The exact output values may vary based on the specific equations provided in your RREF, but that’s the technique you would apply.
