Question:
sir can I use both row and column transformation in 1 Question,means I use column transformation to make 2 zero and then I use row to make other useful results ,it is correct or wrong method?
thank you 😊
Answer:
Yes you can use both row and column transformations in the same question.
But please make sure that you use them in different steps.
For example: R2 → R2 - R1 and C3 → C3 - C2 can not be used together.
Instead do this, R2 → R2 - R1 in first step to get useful results.
Now in the second step, C3 → C3 - C2 to get another useful results.
I hope, it clears your query.
Not what you are looking for? Go ahead and submit the question, we will get back to you.
