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

3x + y = 1
6x + 2y = −9

0

2

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

x can be any value as there are infinitely many solutions to this system

 x can be any value as there are infinitely many solutions to this system

anonymous · Answer

3x + y = 1 ---> y = 1 - 3x 
6x + 2y = −9

6x + 2 (1 - 3x) = -9
6x + 2 - 6x = -9
6x - 6x + 2 = -9
2 = -9. 
This is false. So there is no solution.

There is no x value as there is no solution to this system.
