Q:       Determine the value of the voltage Vo.

Solution:    We want to determine the value of the voltage V₀.  The circuit may be redrawn like  

                        Here from the circuit

                                                 I₁ =3mA

                                    I₂ = 1mA

            By applying KVL for loop 3

                                    4kI₃ + 2k(I₃ +I₂) + 4k(I₃ -I₁) +2k(I₃ - I₁) =6

                                    4kI₃ +2kI₃ +2kI₂ +4kI₃ - 4kI₁ +2kI₃ -2kI₁=6

                                         12kI₃ +2 -1₂ - 6 =12

                                            12kI₃ =22

                                                  I₃ =11/6mA =1.833mA

                                                     V₀ = 4kI₃

                                                    = 4k x 1.833m = 7.33 volts
