Use product `[1-1 2 0 2-3 3-2 4][-2 0 1 9 2-3 6 1-2]`to solve the system of equations`x-y + 2z= 1``2y-3z= 1``3x-2y + 4z = 2`

Text Solution

Verified by Experts

given matrix are `[1-1 2 0 2-3 3-2 4][-2 0 1 9 2-3 6 1-2]`
thus, multiply both of them
`[1 0 0 0 1 0 0 0 1]`
Now, `AB=I`
thus, `A^-1=B`
`A^-1=[-2 0 1 9 2-3 6 1-2]`
From system of equation, we can say that, AX=C
