If `2[(3,4),(5,x)]+[(1,y),(0,1)]=[(7,0),(10,5)]` then

If 2[{:(3,4),(5,x):}]+[{:(1,y),(0,1):}]=[{:(7,0),(10,5):}] , find (x-y).

If [(2,1),(7,4)]A[(-3,2),(5,-3)]=[(1,0),(0,1)] then matrix A equals

If 2[[3,4],[5,x]]+[[1,y],[0,1]]=[[7,0],[10,6]] then find (x-y)

If A=[(2,3,4),(-3,0,2)], B=[(3,-4,-5),(1,2,1)], C=[(5,-1,0),(7,0,3)], then find A+B+C.

If [(1,2,-3),(0,4,5),(0,0,1)][(x),(y),(z)]=[(1),(1),(1)] , then (x, y, z) is equal to

If A=[(1,x),(x^(2),4y)] and B=[(-3,1),(1,0)], adj(A)+B=[(1,0),(0,1)] then the values of x and y are

If [(2x+y,0),(5,x)] = [(5,0),(5,3)] then y is equal to (a) 1 (b) 3 (c) 2 (d) -1

Let A and B be two matrices of the same order 3xx3 such that A=[(-5,1,3),(7,1,-5),(1,-1,1)] and B=[(1,1,2),(3,2,1),(2,1,3)] x+y+2z=1, 3x+2y+z=7 and 2x+y+3z=2 be a system of equatons in x,y,z The value of AB and hence solve the system of equation (A) [(-5,1,5),(21,2,-5),(2,-1,3)] (B) [(4,0,0),(0,4,0),(0,0,4)] (C) [(0,0,1),(0,1,0),(1,0,0)] (D) [(2,-5,1),(1,3,6),(0,0,-0)]
