The problem given in the image involves matrices and the task is to calculate the expression $2A + B + 3C$, where matrices $A$, $B$, and $C$ are defined as follows:

$A = \begin{pmatrix} 4 & -4 \\ 2 & 1 \end{pmatrix}, \quad B = \begin{pmatrix} -3 & -2 \\ -1 & 5 \end{pmatrix}, \quad C = \begin{pmatrix} 5 & 4 \\ -2 & -1 \end{pmatrix}$

We need to compute:

$2A + B + 3C$

Let's break it down step-by-step:

1. First, calculate $2A$ by multiplying matrix $A$ by 2.
2. Then calculate $3C$ by multiplying matrix $C$ by 3.
3. Add the resulting matrices together along with matrix $B$.

I'll perform these calculations now.The result of the matrix operation $2A + B + 3C$ is:

$\begin{pmatrix} 20 & 2 \\ -3 & 4 \end{pmatrix}$
