Find the Thevening Equivalent Circuit for the following circuit:

2. Relevant equations

KVL, KCL.

3. The attempt at a solution

First of all, I calculate the current in the middle mesh, which I'll call i2:

[tex] - j25 = ({i_2} - {i_1})(3 + j4) + {i_2}(10)[/tex]

where i1 is the current defined by the current source. Once I've got i2, I multiply that by 10 to get the voltage in the 10 ohm resistor, and after that I calculate Vab using:

[tex]{V_{ab}} = j25 - 10({i_2})[/tex]

However, the result is incorrect (should be 22,2 V with a 98º angle). What am I doing wrong? I've used the same method with other circuits and it worked just fine.
