If `A=[[2/3, 1, 5/3],[ 1/3, 2/3, 4/3] ,[7/3, 2, 2/3]]`and `B=[[2/3, 3/5, 1],[ 1/5, 2/5, 4/5],[ 7/3, 6/5, 2/5]]`, then compute `3A - 5B`.

Explanation

To compute \(3A - 5B\) for the given matrices \(A\) and \(B\), we will follow these steps:

### Step 1: Compute \(3A\)

Given:
\[
A = \begin{bmatrix}
\frac{2}{3} & 1 & \frac{5}{3} \\
