solve 4x-3y-6=0; x+3y-9=0 graphically

  • math -

    A graphical solution would be achieved by plotting both lines on an x-y graph and seeing where they interesect.

    We lack the tools to do graphing for you.

    By adding the two equations you can eliminate the y variable and see immediatley that

    5x - 15 = 0
    x = 3

    Then use either of your equations for y.

    12 - 3y = 6
    3y = 6
    y = 2
