Solve the following system of equations: - 2x+y=1

-4+y=1

Perhaps you miswrote the question because in your second equation there is no x variable. However, I inferred that you meant to write - 4x+y=1, and was able to solve this system of equations. You can do this either by the substitution method or the graphing method, of which I used the latter. The solution to this system of equations is (0,1). Best wishes!
