If `A=[[1,2,3],[2,3,1]]`and `B=[[3,-1,3],[-1,0,2]]`, then find `2A-B`.

Explanation

To solve the problem of finding \(2A - B\) where \(A = \begin{bmatrix} 1 & 2 & 3 \\ 2 & 3 & 1 \end{bmatrix}\) and \(B = \begin{bmatrix} 3 & -1 & 3 \\ -1 & 0 & 2 \end{bmatrix}\), we will follow these steps:

### Step 1: Multiply matrix \(A\) by 2
We need to multiply each element of matrix \(A\) by 2.

\[ 2A = 2 \times \begin{bmatrix} 1 & 2 & 3 \\ 2 & 3 & 1 \end{bmatrix} = \begin{bmatrix} 2 \times 1 & 2 \times 2 & 2 \times 3 \\ 2 \times 2 & 2 \times 3 & 2 \times 1 \end{bmatrix} \]
