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

3x + y = 6
6x + 2y = 8

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. I got =-12 but no y or x???

3x + y = 6
. . 6x + 2y = 8

-2(3x + y = 6)
. .6x + 2y = 8


-6x - 2y = -12
6x + 2y = 8
--------------------
0 = -4

anonymous · Answer

if you multiply the left side of the first equation by 2, you get the second equation 
but if you multiply 6 by 2 you do not get 8
so there is no solution

That's never true, so there is no x value as there is no solution to the system.
