Given A=[4 9 -2;-3 5 7] and C= [2 -1 -3;1 4 -2], and A+B=C, what is b?
To find the value of B, we can subtract matrix A from both sides of the equation A + B = C:
B = C - A
Given that matrix A is [4 9 -2; -3 5 7] and matrix C is [2 -1 -3; 1 4 -2], we can subtract matrix A from matrix C:
C - A = [2 -1 -3; 1 4 -2] - [4 9 -2; -3 5 7]
Subtracting corresponding elements, we get:
C - A = [-2 -10 -1; 4 -1 -9]
Therefore, matrix B is:
B = [-2 -10 -1; 4 -1 -9]
