Unformatted text preview: isn’t possible to put it into one of these forms then we will know that we are in either the
first or last possibility for the solution to the system.
Before getting into some examples let’s first address how we knew what the solution was based
on these forms of the augmented matrix. Let’s work with the two equation case.
Since, é 1 0 hù

is an augmented matrix we can always convert back to equations. Each row represents and
equation and the first column is the coefficient of x in the equation while the second column is the
coefficient of the y in the equation. The final column is the constant that will be on the right side
of the equation.
So, if we do that for this case we get, (1) x + ( 0 ) y = h
( 0 ) x + (1) y = k Þ x=h Þ y=k and this is exactly what we said the solution was in the previous section.
