There are 3 ways of solving systems linear equations: graphing, substitution, and elimination methods. Search the web and locate and post a system of linear equations in two variable and show your step by step solution using one of the three methods. Don't forget to do a check. Put your solution into the original equation and check that they make both equations true. Why is this important? If your point does not work in your original problem, your solution is not correct. Don't forget to show your check process. Cite the reference in case you are using an example taken from published source. Please answer ALL parts Thank you
