Find x , y , z , t if 2[(x, z ),(y ,t)]+3[(1,-1),( 0, 2)]=3[(3, 5),( 4 ,6)] .

Solve the equation for x,y,z and t, if 2[[x,zy,t]]+3[[1,-10,2]]=3[[3,54,6]]

Value of [[x+y, z,z ],[x, y+z, x],[y, y, z+x]], where x ,y ,z are nonzero real number, is equal to x y z b. 2x y z c. 3x y z d. 4x y z

If we represent the linear equations x + y - z = 3, 2x + 3y + z = 10 and 3x - y - 7z = 1 in matrix form as AX = B, then A^(T) is:

If 2x = 3y = 4z, find x:y: z.

2x + 3y-5z = 7, x + y + z = 6,3x-4y + 2z = 1, then x =

For what values of k the set of equations 2x- 3y + 6z - 5t = 3, y -4z + t=1 , 4x-5y+8z-9t = k has
