If `[[2x+y,z],[1,x-2]]=[[7,2],[1,4]]`,then find x and y

If [[x-y,z],[2x-y,omega]] = [[-1,4], [0,5]], find x,y,z,w

If A=[[3,2,1],[4,-1,2],[7,3,-3]] then find A^(-1) and hence solve the following system of equations : 3x+ 4y+7z= 14, 2x-y+ 3z= 4 and x+ 2y-32= 0.

If [[x-y, 2x+z],[2x-y,3z+omega]] =[[-1,5],[0,13]] find x,y,z,omega

If [[x-y,z2x-y,omega]]=[[-1,24,7]], find x,y,z,omega

If [(x,3x-y),(2x+z,3y-w)]=[(3,2),(4,7)], then find x,y,z,w.

If A=[[1,3,4],[2,1,2],[5,1,1]] , find A^(-1) . Hence solve the system of equations : x+3y+4z=8, 2x+y+2z=5 and 5x+y+z=7

If A=[(2,1,3),(4,-1,0),(-7,2,1)] , find A^(-1) and hence solve the following system of equations: 2x+y+3z=3 4x-y=3 -7x+2y+z=2

If {:[(x-2,y-3),(z+1,t-4)]:}={:[(1,4),(2,3)]:} then find x,y,z and t.

If [(x,3x-y),(2x+z,3y-omega)]=[(3 ,2 ),(4 ,7)] , find x , y , z , omega .

Determine the product [[-4, 4, 4], [-7, 1, 3],[5, -3, -1]][[1, -1, 1],[1, -2, -2],[2, 1, 3]] and use it to solve the system of equations x – y + z = 4, x – 2y – 2z = 9, 2x + y + 3z = 1
