I've been using this site for a while but I finally have a problem that I could not relate to another on this site so here I am!

1. The problem statement, all variables and given/known data

I must calculate the current through R1 given:

R1=3Ω

R2=6Ω

R3=3Ω

R4=4Ω

R5=6Ω

R1 MUST be taken out and thevenin's theorem used.

2. Relevant equations

3. The attempt at a solution

i can't seem to wrap my head around on how to set up the loops. Pulling R1 (which is at a->b) leaves an ugly looking circuit.

Rth =(R2)(R3)/(R2+R3) + R4 + R5

is this thevenin resistance correct? Somebody told me to ignore R5 but that doesn't seem right.

Once i find Vth & Rth I imagine the rest will be simple, kirchhoff's rules & linear equations, etc.
