Answer 1

Answer:

3x - y = 1

Step-by-step explanation:

The system:

$\left \{ {{y = 3x -1} \atop {y = 3x + 2}} \right.$

There is no solution to this system of equations.

The system:

$\left \{ {{y = 3x -1} \atop {3x - y = 2}} \right.$

$\left \{ {{y = 3x -1} \atop { y = 3x-2}} \right.$

The is one solution to this system.

The system:

$\left \{ {{y = 3x -1} \atop {3x - y = 1}} \right.$

$\left \{ {{y = 3x -1} \atop { y = 3x-1}} \right.$

There are infinity solutions to the system.

The system:

$\left \{ {{y = 3x -1} \atop {3x + y = 1} \right.$

$\left \{ {{y = 3x -1} \atop { y = 1-3x}} \right.$

The is one solution to this system.
