Question

, if a=[3 -1,2 4] and b=[1 2,-3 0] ,I=[1 0,0 1] and the equation is 2x+3a-4b=i ,find the value of x​

Answer 1

Answer:

The number of columns of matrix $B$ is equal to the number of columns of the resultant matrix. Here, the number of columns of the resultant matrix is equal to 2. Therefore, the number of columns of matrix $B$ will be equal to 2. Hence, the order of matrix $B$ is equal to $3 \times 2$.
