thnx friends for ur wonderful support!
If you want to know about matrix try thishttp://www.mathsisfun.com/algebra/matri … ction.html
If you mean the matrix bob wrote about,the you have to find d so that det(M)=4,if you mean a linear equation it can be solved like a system of linear equation (but the method would be dull).
His notation is unexplainable. I do not know what to do with it.
it was a chtrm so after that i didnt meet him.
Can you get a little bit more information out of him?
some1 asked me this ques. in a chtrm and i replied the same but then he told me that we have to solve it by using matrix(of which i am totally unaware) and he told me that the answer was 6.

Maybe it really is a matrix such as or Then make det(M) = 4 niharika_kumar: Welcome to the forum. If the above is the sort of thiong you meant, you'll have to make it clear what numbers go where. Bob
Hi niharika_kumar; Is that what you want? Where is the matrix? Please do not say it is all around me... Somebody already got me with that line today.
i am completely unknown to matrix as it has not yet come in my syllabus.But i saw this question somewhere and hence wanted to know the solution.please help me in an easy way so that i get it clearly.
