Some Algebra 1 Questions.. Did I get these right? What is the value of the y variable in the solution to the following system of equations? 3x - 6y = 3 7x - 5y = -11 is it "-2"? What is the value of the x variable in the solution to the following system of equations? 2x - y = 6 4x - 2y = 12 is it "x can be any number as there are infinitely many solutions to the system." or "0"? What is the value of the x variable in the solution to the following system of equations? 4x + 2y = 12 x - y = 3 Is the answer "3"? THANKS

    I figured someone could also check these for me? If you want, they should be easy enough. The graph of a system of equations will intersect at more than 1 point. Always The graph of a system of equations with the same slope will have no solutions. Never (or is it Sometimes...?) The graph of a system of equations will intersect at exactly 1 point. Sometimes

    I would assume if you did these the exact same way. you got it down. So its safe to say your correct

    Well, sometimes I do problems and I mess up something really simple or I use the same method and screw up, soooo it's not safe to say I'm correct XD

    graph of a system. same thing applies if you know this well enough. its always best to go with your first answer is what my american government teacher said..

    3x - 6y = 3 7x - 5y = -11 is it "-2"? yes but plug that back in to either equation to get the other :) x = -3, y = -2 good job :)
