How many solutions does this system of equations have? 2x+y=1 4x+2y=2 a. none b. exactly one c. exactly two d. infinitely many

Given the equations 2x+y=1 and 4x+2y=2, if we divide the second equation by 2, we are left with 2x+y=1, which is the same equation as the first. This means that the lines over lap, and that there are infinite places where they "intercept"
Final
D. Infinitely many

both equations are identical ⇒ D

This does not make sense
