if `A=[[-1,2,3 ] , [2 , 5, 6 ] , [3 , x , 7]]` is a symmetric matrix then find `x`

If the matrix A=[[5 ,2,x], [y, z,-3], [4,t,-7]] is a symmetric matrix, find x ,\ y ,\ z and t .

If [(1,2,-1),(x,3,y),(-1,6,4)] is a symmetric matrix, then find x and y

Find x if A = [[2,3,-1],[x,-5,0],[-1,0,7]] is symmetric matrix

If A = [(1,2,-1),(x, 3, y),(-1,6,4)] is a symmetric matrix, find x,y.

If A=[{:(4,x+2),(2x-3,x+1):}] is symmetric matrix then find x.

A=[[1, 4, -1],[ 2, 5, 4],[ -1, -6, 3]] Write A as the sum of a symmetric matrix and a skew symmetric matrix.

If A = [(-1,2,3),(2,5,6),(3,x,7)] is symmetric, find value of x.

If A=[(2,x-3,x-2),(3,-2,-1),(4,-1,-5)] is a symmetric matrix then x =

IF A=[{:(-1,2,3),(2,5,6),(3,x,7):}] is symmetric, find the value of x

If A=[{:(1, 3/5, x),(y, -5, -7),(-4,-7,0):}] is a symmetric matrix then the value of x and y are ______
