To start we need to consolidate this circuit.

Follow the steps shown below

Step One: Combine 11 ohms and 13 ohms

To combine the two resistors... [(11^-1)+(13^-1)]^-1
the combined resistors equal 5.958 ohms and should be stored in alpha A

Step Two: Combine 3 ohms and A (5.958 ohms).

To combine the two resistors... 3+A
the combined resistors equal 8.958 ohms and should be stored in alpha B

Step Three: Combine 15 ohms and B (8.958 ohms).

To combine the two resistors... [(15^-1)+(B^-1)]^-1
the combined resistors equal 5.60869 ohms and should be stored in alpha C
Step Four: Combine 5 ohms and 7 ohms

To combine the two resistors... 5+7
the combined resistors equal 12 ohms (this numbered does not need to be stored)

Step Five: Combine 12 ohms and 9 ohms

To combine the two resistors... [(12^-1)+(9^-1)]^-1
the combined resistors equal 5.1428 ohms and should be stored in alpha D

Step Six: Combine 4 ohms, D, and C

To combine the three resistors... 4+C+D
the combined resistors equal 14.75 and should be stored in alpha E

Now we can start to find the ammeter values, voltages, and currents.
