If A=((2,2,-4),(-4,2,-4),(2,-1,5))and B=((1,-1,0),(2,3,4),(0,1,2)) , find AB. Hence, solve the following equations x-y=3,2x+3y+4z=17 and y+2z=7

Given that A= [(1,-1,0),(2,3,4),(0,1,2)] and B= [(2,2,-4),(-4,2,-4),(2,-1,5)] , find AB. Using the result solve the following system of equation: x-y=3, 2x+ 3y + 4z=17 and y+2z= 7

Show that each of the following systems of linear equations is consistent and also find their solutions: 6x+4y=2 9x+6y=3 2x+3y=5 6x+9y=15 5x+3y+7z=4 3x+26 y+2z=9 7x+2y+10 z=5 x-y+z=3 2x+y-z=2 -x-2y+2z=1 x+y+z=6 x+2y+3z=14 x+4y+7z=30 2x+2y-2z=1 4x+4y-z=2 6x+6y+2z=3

2x = 3y = 4z, x: y: z

The system 2x + 3y + z= 5, 3x + y + 5z =7, x + 4y -2z=3 has

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

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

Solve by matrix method 3x - 4y + 2z = -1 , 2x + 3y +5z = 7 , x+ z =2
