What is the value of the x variable in the solution to the following system of equations?

2x − y = 6
4x − 2y = 12

0

4

x can be any number as there are infinitely many solutions to the system.

There is no x value as there is no solution to the system

2x-y=6  =>(•(-2)):  -4x+2y=-12
4x-2y=12                4x-2y=12

That it's true so the system of eq. has infinite solution; that means that the two lines are tangent (the one to the other).
