S={(-24,7/3)}
1) When we're dealing with Complex Numbers we can rewrite this expression:

Considering that their real and their imaginary parts can be taken as equal, so:

2) Rewrite that into the Standard form for complex numbers y= ax +bi combining like terms:

Finally writing those two expressions as a System of equations we have:

3) Hence, the answer is S={(-24,7/3)}
