3. Please give a detailed solution on how it is solve.. Please give it step by step.. sorry for the inconvenience because I am still new at this.. thank you

Problem 3 Vs 10 V I₁ R₁ 8 Ω +21 V2 12 R₂ 3 Ω + m ww 6Ω Figure P3 By using only network theorems and their properties, and also voltage and current divider formulas, solve the circuit in Figure P3 following the steps below: a) Obtain the equivalent resistance Reqt of the resistor network in the circuit. b) Based on Reql determine the current I1 of resistor R₁. c) What is the direction and magnitude of current in the voltage source? Why? d) What type of a network is the resistor network formed by R2 and R3? Obtain their equivalent resistance Req2. What are voltages v2 and v3 using the voltage divider formula? e) f) Current I₂ can be obtained by dividing current I₁ between currents in R₂ and R3 using the current divider formula.

I am not sure how to do the nodal analysis on this problem.
