Which could be the resulting equation when elimination is used to solve the given system of equations? 5 A plus 5 b is equal to 25 negative 5 A plus 5 b is equal to 35

Add the equations: (5a + 5b) + (−5a + 5b) = 25 + 35. The a-terms cancel, leaving 10b = 60. So the resulting equation is “10b is equal to 60,” choice D.
