on a line the distance between 2x and 7x plus 80 is 142. Solve for x

  • grade 10 math -

    7x+80 - 2x = 142
    5x = 62

    thank you oh so much.. means much

  • grade 10 math -

    so.. solving for x.. does not give a whole number?

    in this case, apparently not. Seems a bit odd, but that's so.

    I'm assuming your question can be parsed as

    distance between (2x) and (7x+80)

    That would indeed be the larger minus the smaller, or 5x+80

    i really appreciate this
