** Using Norton here is silly and time wasting.

It is simply a parallel resistor problem.

1. RL plus R3 parallel R 5 - so compute the combined value.

2. This value plus R2 parallel R4 - so compute the value.

You can simplify this circuit a lot by applying the rules for parallel and
series resistors repeatedly.

treat the voltage source as a short circuit (or as a fixed resistor if
it has non-zero resistance) and solve for the resitance at the part that
interests you (this would be the output terminals)

Try thevenin that is a snap. look up thevenin theory.

You are lucky today.
Usually its not easy to get someone to do your homework for you.

Exactly so. Norton's theorem applies to a two-terminal device
consisting of voltage sources and resistors. Tell us _which_ two
terminals of the seven, or there isn't any soluble problem presented.
