Finding voltages and currents on diodes
Simplest way to do diodes is to remove them and calculate the voltages as shown on the left.

Now put the diodes back.

D2 will be conducting because the voltage at the top on the left is higher than the 0.7V required to turn it on. Note new voltages on right drawing.

Now you only have .5V across D1, so .... Is it on or off?
