solve the following using substitution
so what do i do now?
Those two equations are the same.
Look at your first equation dividing both sides by 4
2 x - y = 4 or y = 2x-4 which is the second equation exactly. There is no intersection of a line with itself in a point. The system of two equations given has no solution.
Thank you that is what I thought but wasn't sure when I did not come up with an answer.
