Given A=( 3 2 5) ( 2 -1 8)
(4 7 -3 )and c=(5 0 3), find B if A+B=C
Sorry, I don't get it.
Is A a square matrix and B and C columns or what?
do you mean A * B or A + B ???
A+B
Are they matrices? is A square and C a column?
A and B
| 3 2 5 | |B11 B12 B13| |5|
| 2 -1 8|+|B21 B22 B23|=|0|
| 4 7 -3| |B31 B32 B33| |3|
Is that what you mean ??? or what ?
-1 -3 -3
1-7 6
-1 -3 3
1 -7 6
1 -3 3
-1 -7-6
-1-3 3
1 7 6
A B C or D?
I still do not have any idea what the question is.
To find matrix B, we need to subtract matrix A from matrix C.
Let's calculate the difference:
C - A = (5 0 3) - ( 3 2 5) ( 2 -1 8)
(4 7 -3 )
To subtract two matrices, we subtract corresponding elements in each matrix.
C - A = (5-3 0-2 3-5) (2-2 -1-(-1) 8-5)
(4-4 7-7 -3-(-3))
Simplifying further, we get:
C - A = (2 -2 -2) (0 0 3)
Therefore, B = C - A = (2 -2 -2) (0 0 3)
