Consider the circuit on the left. You are not given the values of
V_(S),I_(S),R_(1),R_(2)or
R_(3). You are told the value of current
i_(1)if
V_(1)is attached to this circuit, with A connected to
A^(')and B connected to B'. You are also told the value of current
i_(2)if
V_(2)is attached, with A connected to
A^('')and B connected to
B^(''). However, in this case, the independent sources were first turned off (i.e.,
V_(S)=0and
I_(S)=0). Your task is to find
V_(x)if current source
I_(3)is connected to the original circuit (i.e., with the independent sources
V_(S)and
I_(S)not turned off), with A connected to
A^(''')and B connected to
B^('''). Given Variables:
 V1:6 V 
i1:12A
V2:12V
 i2: 12A
 I3:-7 A R4: 2 ohm Calculate the following:
Vx(V):
