    Lol. C is always the correct answer, but not this time.

    You could graph it the 2 equations using https://www.desmos.com/calculator and see which ones don't have any shaded area common to both equations.

    Don't let the less than greater than confuse you in these questions, set it up as you would regularly with a equation of a line y = mx+b just with a few rules, which can be found here: https://www.mathsisfun.com/algebra/inequality-properties.html

    You can see it has a shaded area (which is common to both) that shows it does have a solution. Which answer choice gives you a graph that has no common shaded area?
