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

Problem

Geoffrey and Amara'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.
Teacher
6, x, minus, 5, y, equals, 1
minus, 2, x, plus, 2, y, equals, minus, 1
GeoffreyAmara
6, x, minus, 5, y, equals, 14, x, minus, 3, x, equals, 0
14, x, minus, 14, y, equals, 7minus, 2, x, plus, 2, y, equals, 1
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.
