Express the following system of simultaneous linear equation as a matrix equation: `2x+3y-z=1,\ \ x+y+2z=2,\ \ 2x-y+z=3`

Explanation

We have given the simultaneous linear equation as
`2x+3y-z=1,\ \ x+y+2z=2,\ \ 2x-y+z=3`

Then we have to write it in matrix form

We can write the given equation in the matrix form `AX=B` as

`[(2,3,-1),(1,1,2),(2,1,1)][(x),(y),(z)]=[(1),(2),(3)]`

where,

`A=[(2,3,-1),(1,1,2),(2,1,1)]`,
`X=[(x),(y),(z)]`,
