Circuit Analysis Question
Since this is school work, direct answers are strongly discouraged.  Here is some guidance to "see" the problem more clearly.


Assign reference designators to each component.  Assign a GND symbol to the 10 V negative node.
Anywhere there are two or more resistors in series without any connections to the joining nodes, combine them.
Anywhere there are two or more resistors in direct parallel, combine them.
Redraw the schematic so all resistors are either vertical or horizontal.  See the way the two resistors connected to GND are spaced apart for clarity?  Do that for the +10 V node.
Now the current paths should be easier to see and discuss.
