I am having problems solving these resistor problems and was wondering if anyone could help. Really what I think my problem is is that i don't know what to do if there are series and parallel resistors on the same circuit

For attachment three The resistance of the entire circuit and RL are supposed to be equal to each other and then you are wanting to find the resistance of R to make that true. The actual problem used RAB = RL = 625. ohms. and you are supposed to get 361 for R, but my numbers are all over the board and i can't hit that, because i don't know what to do with the resistor inbetween the 2 parallel resistors.

then for attachment 6.jpg if i know the voltage of the circuit and the ohms of the resistors i am supposed to find the current.

In the practice problem i am trying to find out my numbers are

If the resistances R1= 44. ohms, R2 = 14. ohms, and R3 = 26. ohms, and the voltage V = 6.0 volts, what is the current ix (in Amperes) in the circuit.

The answer i am given is 4A, but i keep coming up with .11
