3 possibilities are possible with a system of equations.

Scenario I - Infinite Solutions (All real numbers)

The linear equations the same.

Scenario II - No solution

The linear equations are parallel so they never touch.

Scenario III - 1 solution

The linear equations intersect and the ordered pair is the solution.

Please see the video example below.
