X = 12 subtract then divide both sides
A 2 x 2 matrix has 2 rows and 2 columns
A specific 2 x 2 matrix a with no zero entries at all is ![\left[\begin{array}{cc}1&-2\\-3&6&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%26-2%5C%5C-3%266%26%5Cend%7Barray%7D%5Cright%5D)
<h3>How to construct the matrix?</h3>
From the question, we understand that the matrix is a 2 x 2 matrix.
A 2 x 2 matrix is represented as:
![\left[\begin{array}{cc}a&b\\c&d&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Da%26b%5C%5Cc%26d%26%5Cend%7Barray%7D%5Cright%5D)
Also from the question we understand that the elements of the matrix are non-zero.
This means that:

An example of such matrix is:
![\left[\begin{array}{cc}1&-2\\-3&6&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D1%26-2%5C%5C-3%266%26%5Cend%7Barray%7D%5Cright%5D)
Note that there are several matrices that fit the given construction requirement

Answer:
m = 5.1
Step-by-step explanation:
m + 2 = 7.1
Subtract 2 from both sides: m = 5.1
