Langkah Penyelesaian dan Jawaban :
[tex] \left[\begin{array}{ccc}x + 1&5\\y - 2&3\end{array}\right] + \left[\begin{array}{ccc}4 &y + z\\2&5\end{array}\right] = \left[\begin{array}{ccc}0&- 6\\5&8\end{array}\right] \\ \\ \left[\begin{array}{ccc}x + 1 + 4&5 + y + z\\y - 2 + 2&3 + 5\end{array}\right] = \left[\begin{array}{ccc}0&- 6\\5&8\end{array}\right] \\ \\ x + 5 = 0 \\ x = - 5 \\ \\ y - 2 + 2 = 5 \\ y = 5 \\ \\ 5 + y + z = - 6 \\ 5 + 5 + z = - 6 \\ 10 + z = - 6 \\ z = - 16[/tex]
