Two systems of equations are shown below. The first equation in System B is the original equation in system A. The second equati
on in System B is the sum of that equation and a multiple of the second equation in System A. A. x + 3y = 11 → x + 3y = 11
5x − y = 17 → 15x − 3y = 51
15x = 62
B. x + 3y = 11
15x = 62
