    Circuit Analysis. Find V0 in the network

    1. The problem statement, all variables and given/known data

    I need to find V0


    2. Relevant equations

    I need to find V0

    3. The attempt at a solution


    I did KVL.
    13 +Vx - 4Vx + 2I +2VA <----- 1st equation
    Vx = 7I <----- 2nd equation
    VA = 2I +2VA <----- 3ed equation


    solve 3e eq. i got I = 1.5VA
    then used that answer to solve 2nd eq. i got Vx = -3.5 VA

    then i apply both those answers to solve 1st eq

    13 -3.5VA + 14 VA -VA +2 VA =0
    VA = -13/11= -1.13

    therefore V0 = 2VA= 2.26V


    Am i right?
