I'm trying to solve some problems for a homework assignment and I'm a bit confused. For each question, they want me to determine if the equations are NOT a linear system and why. They are formatted like this:
-2x + 3y = 7.5
7x - 2y = -2.5
They want me to compare the equations and determine if they represent a linear system. I know how to do this when coordinates are given for x and y, but I'm not sure how to go about this when the variables x and y are unknown. Can someone help?
