Determine whether each system is independent, inconsistent, or dependent. 2x - y = 6 -4x + 2y =9This question is from textbook College Algebra Answer by fractalier(2101)   (Show Source): You can put this solution on YOUR website!From 2x - y = 6 -4x + 2y = 9 let us multiply the top one by two and add them...we get 2(2x - y = 6) -4x + 2y =9 and 4x - 2y = 12 -4x + 2y = 9 adding we get 0 = 21 We ask, "When does 0 = 21?" Well never of course. Thus this system has no solution, the lines are parallel and the system is inconsisent.
