Solve the system of equations by substitution. What is the solution for x?
2x + y = 1
4x + 2y = -1

x=0
x=2
There is no x value, as there is no solution.
x can be any value, as there is an infinite number of solutions.

here is a little help

2x + y = 1       in slope intercept for its    y = -2x + 1

4x + 2y = -1  in slope intercept form its  y = -2x - 1/2 

what do you notice about the 2 lines..?
