Solve the system of equations

\(2x_{1}+x_{2}+2x_{3}+x_{4}=6\)

\(4x_{1}+3x_{2}+3x_{3}-3x_{4}=-1\)

\(6x_{1}-6x_{2}+6x_{3}+12x_{4}=36\)

\(2x_{1}+2x_{2}-x_{3}+x_{4}=10\)

Using matrix mathod , show that the equations

3x+3y+2z=1,

x+2y=4,

10y+3z=-2,

2x-3y-z=5

are consistent and hence obtain the solution for x,y,and z.

For what value of the parameter \(\lambda ,\mu\)do the system of equations

1) no solution 

2) unique solution

3) more than one solution

\(x+y+z=6,x+2y+3z=10,x+2y+\lambda{z}=\mu\)
