Find the current on the 20 ohm resistor.

Homework Equations

The Attempt at a Solution

Well, I'm fairly positive that the two 10 ohm resistors will transport the same amount of current so:

25V - I*25 - I2*10 = 0
25V + I3*5 - 10*I2 = 0
I = 2*I2 + I3

When I solve using those equations, I get I2 = 1.36 A and I = .45 A (I is double of what it should be).
Could anyone look at my equations and tell me what's wrong?

Reduce the circuit as much as possible. You put the 5 ohm and 20 ohm in series already. There is also the 5 ohm and 10 ohm that are in parallel. If you reduce that you will then have a circuit with two loops. Then you will only have two unknowns to deal with.

Ok, now I've got it, thanks
