[x+y=6;x-y=4],[(6,0)*((4,0)/(0,-4))],[(0,6)]

Given the matrix A=[(x,3,2),(1,y,4),(2,2z)]. If xyz=60 and 8x+4y+3z=20, then A(adjA) is equal to (a) [(6,4,0,0),(0,6,4,0),(0,0,6,4)] (b) [(8,8,0,0),(0,8,8,0),(0,0,8,8)] (c) [(6,8,0,0),(0,6,8,0),(0,0,6,8)] (d) [(3,4,0,0),(0,3,4,0),(0,0,3,4)]

Find X and Y if X-Y=[(2,1),(4,3),(0,6)] and X+Y=[(12,13),(6,5),(4,8)]

If [(x y,4),(z+6,x+y)]=[(8,w),(0, 6)] , write the value of (x+y+z) .

If [(x y,4),(z+6,x+y)]=[(8,w),(0, 6)] , write the value of (x+y+z) .

If [(2x+y,3y),(0, 4)]=[(6, 0),( 6, 4)] , then find x .

If [{:(x, 0), (0, y):}] + [{:(-y, 4),(7, x):}] = [{:(4, 4), (7, 6):}] then x = ____ and y=___.

Find X and Y if X-Y = [(2,1),(4,3),(0,6)] and X+Y = [(12,13),(6,5),(4,8)]

If [{:(xy,4),(z+6,x+y):}]=[{:(8,w),(0,6):}] , then find values of x,y,z and w.
