How Do You Solve a Basic KVL Circuit Problem?

the work i did on that sheet is completely wrong.

I know that Ic = Ia + Ib

but can someone help me set up the equations for the two loops please! I can't seem to figure it out and its frustrating me!

the answer is supposed to be Ic = (RbE1 + RaE2) / RaRb + RaRc + RbRc

Write the KVL equation for the "left loop".

Write the KVL equation for the "right loop".

Write the KCL equation for either junction.

thanks i just figured it out. this is just an intense algebra problem!

Yes. Algebra is involved.
