To find the order of the matrix \( 7X - 5Z \) given that \( n = p \), we can follow these steps: ### Step 1: Determine the order of matrices \( X \) and \( Z \). - We know from the problem statement that the order of matrix \( X \) is \( 2 \times n \). - Similarly, the order of matrix \( Z \) is \( 2 \times p \). ### Step 2: Substitute \( n = p \). - Since it is given that \( n = p \), we can replace \( p \) with \( n \) in the order of \( Z \). ...
