Ren was trying to solve a system of linear equations. He correctly argued that he could replace one equation by the sum of that equation and a multiple of the other. He stated that this would produce a system that has the same solution as the original system. To show this, Ren wrote down a system of equations. He then determined which other systems of equations would have the same solution as his original system. Ren's original system is shown below. -2x - 5y =-47 4x - 2y =-2
