Using the Superposition principle to solve a linear circuit

[Gabry89]

I tried it many times but i don't understand how to start and which are the first steps.

I started like this:

Solve for V1:

V_r1 = V1 * (R1/R1+(R2||(R3+R4))) = 5 V

I'₁ = V_r1/R1 = 1 A

I'₂ = I'₁ * [(R1+R2)||(R3+R4)]/(R3+R4) = 0,6 A.

is that right?

It is kinda difficult 'cause i must use the superposition.

The results should be i1= 0,5 A and i2= 0,65 A

Solved, it was not so difficult, anyway the formulas in the first post are wrong. You just have to be careful using the voltage divider and the KCL, KVL. The thread can be closed.
