# Is it possible to put a system of equations parallel to the matrix?

$$4T_1-T_2 - T_4 = 30$$
$$-T_1+4T_2 -T_3 = 60$$
$$-T_2 + 4T_3 + T_4 = 70$$
$$-T_1 + T_3 + 4T_4 = 40$$

Is it possible to put the above system of equations parallel to right side of the below matrix?

$$\begin{bmatrix} 4 & -1 & 0 & -1 & 30 \\ -1 & 4 & -1 & 0 & 60 \\ 0 & -1 & 4 & 1 & 70 \\ -1 & 0 & 1 & 4 & 40 \\ \end{bmatrix}$$

{Finished]

$$\begin{array}{rcl} 4T_1-T_2 - T_4 &=& 30 \\ -T_1+4T_2 -T_3 &=& 60\\ -T_2 + 4T_3 - T_4 &=& 70\\ -T_1 - T_3 + 4T_4 &=& 40\\ \end{array} \qquad \begin{bmatrix} 4 & -1 & 0 & -1 & 30 \\ -1 & 4 & -1 & 0 & 60 \\ 0 & -1 & 4 & -1 & 70 \\ -1 & 0 & -1 & 4 & 40 \\ \end{bmatrix} \space \begin{array}{rcl} R_1 &↔& R_4 \\ R_2 &↔&R_3 \\ \\ \\ \end{array}$$
