Solve the following system of homogeneous equations: `x+y+z=0` `x-2y+z=0` `3x+6y-5z=0`

Text Solution

Verified by Experts

We have given :the system of homogeneous equations:`x+y+z=0``x-2y+z=0` `3x+6y-5z=0`
It can be written in matrix form as
`A=[(1,1,-1),(1,-2,1),(3,6,-5)]`
Now apply `R_2->R_2-R_1`and `R_3->R_3-3R_1`
`A=[(1,1,-1),(0,-3,2),(0,3,-2)]`
`|A|=0` and rank of `A=2`, submatrix is `[(1,1),(0,-3)]`
Hence we get
