    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: \[x=12\]
