What will be the ans in case of rank is Greater than the number of variables in the matrix?

-x +5y = -1

3x -7y = 2

X + 8 y = 3

In this case rank (3) > number of variables (2) .

Now what will be the ans?

-x +5y = -1

3x -7y = 2

X + 8 y = 3

In this case rank (3) > number of variables (2) .

Now what will be the ans?
