If A=[[(4)/(5),(3)/(5)],[x,(4)/(5)]] and A^(T)=A^(-1) then x is :

Find the inverse of the matrix: [[1,2,3],[2,4,5],[3,5,6]] . Hence solve the equations x+2y+3z = 2 , 2x+4y+5z = 1 , 3x+5y+6z = 3 .

If A={:[(1,2,3),(4,5,6)]:} , then A^(T) = ________ .

If |[2,4],[5,1]|=|[2x,4],[6,x]| then x is

Find x, if [[5,3x],[2y,z]]=[[5,4],[12,6]]^(T) .

If A = [(5, -1, 4), (2, 3, 5), (5, -2, 6)] , find A^(-1) and use it to solve the following system of equation 5x - y + 4z = 5, 2x + 3y +5z = 2, 5x - 2y + 6z =-1

If A = [(5, -1, 4), (2, 3, 5), (5, -2, 6)] , find A^(-1) and use it to solve the following system of equation 5x - y + 4z = 5, 2x + 3y +5z = 2, 5x - 2y + 6z =-1
