The easiest way would be to learn the material. Any chance we can try a problem and figure that out?
I am having trouble with how to solve linear equations and functions, as well as how to do systems of equations(as listed in the title). I can't really seem to figure out what I am supposed to be doing, I have a test tomorrow! I've been searching everywhere for a source of good information regarding ways to do these (linear equations, functions, system of equations).
Please; if you guys know an easier way to do these (linear equations, functions, system of equations), leave a comment below.
MHF cannot provide a crash course the night before a test. The fact that you are unable to graph the two linear equations you gave as an example suggests that your lack of understandng is extensive.
I suggest you start getting regular on-on-one help from your instructor or a tutor. Also, your class notes and textbook, ought to contain plenty of examples to follow. And Google will turn up hundreds of websites that can help you.
