I am working with the following equation:(adsbygoogle = window.adsbygoogle || []).push({});

|1 -2 3|

|6 -11 15|

|4 -14 21|

a. add -4 time Row1 to Row 3

b. add -6 times Row 1 to Row 2

c. add 6 times Row 2 to Row 3

d. multiply row 3 by -1/9

I have come up with the following answer:

|24 -48 72|

|180 -354 522|

|-19.99 39.99 -58.99|

Where did I go wrong?
