I have a trick question, I am in week three and solving systems of linear equations with 2 variables using either the elimination method or the substitution method and then graphing. My problem on the test is missing the second variable, how do I create new equations containing them so that I can solve and graph? My equations are: 4x = 8 and 5y = 15
