Part 1: If you were solving a system of equations and you came to a statement like 1 = 3, what do you know about the solution(s) to this system? Part 2: Solve the following system and show all of your work. x - 2y = 14 x + 3y = 9

    Part 1: the solutions don't exist, or equivalently the system is inconsistent. For part two, I would use a matrix method to encode the coefficients and row-reduce it, but because I don't want to write it out in this text format, we will just use elimination: subtract equation two from equation one: \[-5y = 5 \Longrightarrow y=-1\] Sub y=-1 into either equation to get: \[x=12\]
