Given A=[4−395−27] and C=[21−14−3−2] , and A + B = C, what is B?
To solve for B, we need to find the missing values in the matrix B that makes the equation A + B = C true.
Given that A = [4 -3 9; -2 5 -2] and C = [2 1 -8; -1 3 -5].
To find B, we can subtract matrix A from C:
C - A = B
[2 1 -8] - [4 -3 9] = B
[2-4 1+3 -8-9] = B
[-2 4 -17] = B
Therefore, B = [-2 4 -17].
