    for graphing, visit
    http://rechneronline.de/function-graphs/

    I get C,A,B
    Just plug in the numbers to make sure they work!

    #5 is correct

    #6
    2x - 1 = x+3
    x = 4 , y = 7
    looks like A)

    #7
    4x = 5-x
    5x=5
    x=1 , y = 4
    looks like B)

    You should have checked each of your answers by simply subbing your answer. It must satisfy BOTH equations
