Dear student
4+ y =0
and
x+ 1 = 5
So ,y =-4 and x =4
X -y = 4-(-4) = 8
Hope this helps
Good luck
Cheers

hello tech mirror, as usual vikas has given you the wrong ans, which clearly shows poor quality of his answers. the correct method is as follows:
since the first matrix is multiplied by 2, its elements become 6, 8, 10 and 2x. after adding the second matrix, the final elements become 6+1, 8+y, 10+0, 2x+1, which must be equal to 7, 0, 10, 5 respectively.
so, 8+y= 0 and 2x+1= 5
or y= – 8 and x= 2
so x – y= 10
kindly approve :)
