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 system has the same solution as the teacher's system?
