Please help!!!!

Compute the following quantity for this circuit using source transformations:

I$$

Once you perform any medification on an element that is part of a

combinable series or parallel set or removable set, you must first finish

that set before you can perform any actions on any other set.

Likewise, once you madify a source or passive element that you wish

to transform, you must complete that transfermation before doing

anything else. If you want ta begin work on anather set without first

finishing the set you started, press the "Restare Circuit" button to

restore the circuit to your last valid combination, removal, or

transformation.
