Solve the following system of equations using Cramers rule. 5x-7y+z=11 , 6x-8y-z=15 and 3x+2y-6z=7

Solve the system: x + y - 2z = 0, 2x - 3y + z = 0, 3x - 7y + 10z = 0, 6x - 9y + 10z = 0.

If x =a, y=b, z=c is a solution of the system of linear equations x + 8y + 7z =0, 9 x + 2y + 3z =0, x + y+z=0 such that point (a,b,c ) lies on the plane x + 2y + z=6, then 2a+ b+c equals

If x =a, y=b, z=c is a solution of the system of linear equations x + 8y + 7z =0, 9 x + 2y + 3z =0, x + y+z=0 such that point (a,b,c ) lies on the plane x + 2y + z=6, then 2a+ b+c equals

Add : 8x - 3y + 7z, -4x + 5y - 4z, -x - y - 2z

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

x+2y-2z=5,3x-y+z=8,x+y-z=4
