True or False
If` (x-2,y+5) = (-2,1/3), `then x = 4, `y = -(14)/3`

True or false The line x=y=z lies in the plane x-2y+z-1=0.

If [(x-y, z),(2x-y, w)] = [(-1,4),(0,5)] , find x , y , z and w.

State whether the following statements are true or false. (x -y) (x +y) = x ^(2) + y ^(2)

If A = [[2,-3,5],[3,2,-4],[1,1,-2]] find A^-1 . Using A^-1 solve the system of equations 2x-3y+5z = 11, 3x+2y-4z = -5, x+y-2z = -3

State True/False: The point (1,2) satisfies 2x + y ge 5

If (x/3+1, y-2/3)=(5/3, 1/3) , find the values of x and y.

Find Y,if X = {:[(3,2),(1,4)] and 2X + Y = [(1,0),(-3,2)]
