What is the value of x in the solution to this system of equations?
у + 2x = — 1
у = х +4

I believe the answer is -5/3

Y+2x=-1 could become y=-2x-1 and then set that and x+4 equal to each other -2x-1=x+4 and add 2x to both sides to get -1=3x+4 and subtract by 4 on both sides to get -5=3x then divide by 3 and get -5/3=x

He is right i did this thing before

The correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)
