m × n(X) = m×n(Y) = 2×3
m×n(7X) = 2×3
m×n(5Y) = 2×3
m×n(7X - 5Y) = 2×3
I think it's correct

Answer:
Since the matrix is subtraction..the order of matrix doesn't change while we calculating addition and subtraction matrix...since the order of x ,y matrix is 2*3...i.e., the order of 7x-5y matrix is also of order 2*3...
I think it's a right method to think...
If there is any mistake please forgive because first time i am typing the answer to the question in Google..
Thank you..
