(B) a square matrix
Explanation:
The given Equations are:
,
and

Which can be written as:
![\left[\begin{array}{ccc}3&-2&2\\7&3&-26\\-1&-11&46\end{array}\right]](https://img.qammunity.org/2020/formulas/mathematics/middle-school/urwdw1l51qh0mkqbrka8qshy36vwa2sk36.png)
Thus, it is a matrix with 3 number of rows and 3 number of columns, therefore the matrix which has same number of rows and columns is a square matrix, thus, a square matrix can be form using the given system of linear equations.
