[" If the matuix "A=[[5,2,x],[y,z,-3],[4,t,-7]]" is a symometric matuir "],[" lind "x,y,2" and "t" ."]

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

If {:[(x-2,y-3),(z+1,t-4)]:}={:[(1,4),(2,3)]:} then find x,y,z and t.

If {:[(x-2,y-3),(z+1,t-4)]:}={:[(1,4),(2,3)]:} then find x,y,z and t.

If [[x,y],[x,x/2+t]]+[[y,x+t],[x+2,x/2]]=[[1,4],[2,3]] find x,y,z and t.

If [(x+y,y-z),(5-t,7+x)]=[(t-x,z-t),(z-y,x+z+t)] , then find the values of x, y, z and t.

find the values of x,y,z and t when the following matrices are equal : {:[(x+y,y-z),(5-t,7+x)]and {:[(t-x,z-t),(z-y,x+z+t)]

If t is real and lambda = (t^2-3t+4)/(t^2+3t+4) then find number of the solution of the systems of equation 3x-y+4z =0,x+2y-3z=-2.6x+5y+lambda z=-3 for a particular value of lambda .

Solve the equation for x, y, z and t , if 2[[x, z],[ y, t]]+3[[1, -1],[ 0, 2]]=3[[3 , 5 ],[ 4, 6]]
