Solve the following system of equations, using matrix method. `x+2y+z=7,x+3z=11 ,2x-3y=1`

Explanation

We have given

`x+2y+z=7`,

`x+3z=11` ,

`2x-3y=1`

We can write them in matrix from AX=B....(i)

`[(1,2,1),(1,0,3),(2,-3,0)][(x),(y),(z)]=[(7),(11),(1)]`

Determinant of matrix A,

`∣A∣=|(1,2,1),(1,0,3),(2,-3,0)|`
