i have this circuit (see attached) and i am wondering if anyone has run into an online calculator that would solve this for me, or if you could post the equation that i need to solve this problem. I would like to know what my voltages should be at points X, and Y on the attached pdf.
but - (and i forgot to include this in the original post) the volts i measure at X, and Y of this circuit using a scope is right about 1.4v - thus the need to ask the original question.

The scope is not No-load. It adds a load equal to its input resistance (typically 1M ohm direct or 10M ohm with a 10:1 probe). But either of those is small compared to 10k ohm, so its effect here is minimal.
exactly what i was thinking Carl, the scope shouldnt change it this much - but yet i am reading 1.4v and havent found the reason for it - i have replace all 4 resistors with known correct ones (i ohm tested each of them) and set this up again - and i get the same thing.... darn 1.4v!!
