Determine whether a couple of given systems of equations are equivalent or not to a third given system.


Lucius and Angelina's teacher gave them a system of linear equations to solve. They each took a few steps that led to the systems shown in the table below.
5, x, plus, 2, y, equals, 4
4, x, plus, y, equals, 2
4, x, plus, y, equals, minus, 212, x, plus, 3, y, equals, 6
10, x, plus, 4, y, equals, 85, x, plus, 2, y, equals, 4
Which of them obtained a system that is equivalent to the teacher's system?
Remember that two linear systems are "equivalent" if they have the same solution.
