[6x-9y-20z,=-4],[4x-15y+10z,=-1],[2x-3y-5z,=-1]

Use matrix methocd to solve the following system of equations: {:(6x - 9y - 20 z = -4), (4x - 15 y + 10z = -1),(2x - 3y - 5z = -1):}

x+y+z=4 2x-y+z=-1 2x+y-3z=-9

Using determinants, show that the following system of linear equation is inconsistent: x-3y+5z=4 , 2x-6y+10 z=11 , 3x-9y+15 z=12

Solve the following system of equations by matrix method: 6x-12 y+25 z=4,\ \ 4x+15 y-20 z=3,\ \ 2x+18 y+15 z=10

4x -5y-11z=12,. x-3y+z=1 2x + 3y-7z = 2

Using determinants, show that the following system of linear equation is inconsistent: x-3y+5z=4 2x-6y+10 z=11 3x-9y+15 z=12

Using determinants,show that the following system of linear equation is inconsistent: x-3y+5z=42x-6y+10z=113x-9y+15z=12
