Let A=` [[3,0,5,6,-2],[-2,-5,0,1,y],[5,2,x,8,0],[0,-3,2,3,-5],[-4,-7,-2,-1,-9]]` is `5xx5` Square matrix.
Each row and column of matrix A has a value assigned to it. Every element is the sum of its row and column values. For example – 9 is the sum of the value assigned to 5^th row and 5^th column. Then the value of x + y is-
