Ooops, Băd mistake aboveYou have to try something
1st column a b c
2nd column d e f
3rd column g h i
4th column j k l
a + b + c = 1
d + e + f = 1
g + h + i = 1
j + k + l = 1
a + b = c, d + e = f, g + h = i, j + k + l
All I did was what they told me to do.
The question is can you find A, B and C?
Did you post the entire problem?
Picture the matrix A. What column matrix could you multiply it by on the right to get a column matrix whose entries are the sums of the entries in each row of A? If A satisfies the first condition, this product will be all 1's.View attachment 34035
I literally dont even know where to start. Any and all help is very much welcome!
But you did not write "rows" anywhere in that post!!! See belowOoops, Băd mistake above
Where I wrote rows, I should have written column.
1st column a b c
2nd column d e f
3rd column g h i
4th column j k l
a + b + c = 1
d + e + f = 1
g + h + i = 1
j + k + l = 1
a + b = c, d + e = f, g + h = i, j + k + l
All I did was what they told me to do.

Did you post the entire problem?
What can I say other than I suffer from dyslexia.But you did not write "rows" anywhere in that post!!! See below
Now I understand the problem!Yes that is the entire problem, here is the solution as well, I just don't know how to get there...View attachment 34036
