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

7x+80  2x = 142
5x = 62
... 
thank you oh so much.. means much

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
