Answer:

Infinitely Many Solutions

Step-by-step explanation:

Given

[tex]\left[\begin{array}{cccccc}1&2&3&4&5&6\\7&6&5&4&3&2\\8&8&8&8&8&8\end{array}\right][/tex]

Required

Determine the type of solution

From the matrix, we have:

3 non-zero rows and 5 variables (the last column is the result)

When the number of variables is more than the number of non-zero rows, then such system has infinitely many solutions

i.e.

[tex]Variables > Non\ zero\ rows[/tex]

[tex]5 > 3[/tex]
