Solve the system of equations by substitution. What is the solution for x?

2x + y = 1
4x + 2y = −2

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.

divide the second equation by 2, and you'll have 2x+y=-1. rearrange both equations to put y on the left side:
y= -2x+1
y= -2x-1
you can probably see the answer from this?

i got 8x= -5 but that cant be right
cause the answers a fraction
