Question 175531
<pre>

start with augmented matrix
:
{{{(matrix(2,3,3,5,7,6,-1,-8))}}}(R1)/3{{{(matrix(2,3,1,5/3,7/3,6,-1,-8))}}}-6R1+R2{{{(matrix(2,3,1,5/3,7/3,0,-11,-22))}}}R2/-11{{{(matrix(2,3,1,5/3,7/3,0,1,2))}}}-(5/3)R2+R1{{{highlight((matrix(2,3,1,0,-1,0,1,2)))}}}
:
answer is {{{system(x=-1,y=2)}}}

remember that R1 is Row 1
.................R2 is Row 2
:
and when you see something like R1/3 that is all the elements in Row 1 being divided by 3.  Maybe you'll see 6R1+R2..thats elements in Row 1 multiplied by 6 and added to elements in Row 2.
