I need to find V0

Homework Equations

I need to find V₀

The Attempt at a Solution

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


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

then i apply both those answers to solve 1st eq

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

therefore V₀ = 2V_A= 2.26V


Am i right?
