Solving
-2 + -1i + -1z + -1zI + z2 = 0

Solving for variable 'i'.

Move all terms containing i to the left, all other terms to the right.

Add '2' to each side of the equation.
-2 + -1i + -1z + -1zI + 2 + z2 = 0 + 2

Reorder the terms:
-2 + 2 + -1i + -1z + -1zI + z2 = 0 + 2

Combine like terms: -2 + 2 = 0
0 + -1i + -1z + -1zI + z2 = 0 + 2
-1i + -1z + -1zI + z2 = 0 + 2

Combine like terms: 0 + 2 = 2
-1i + -1z + -1zI + z2 = 2

Add 'z' to each side of the equation.
-1i + -1z + -1zI + z + z2 = 2 + z

-1i + -1z + z + -1zI + z2 = 2 + z

Combine like terms: -1z + z = 0
-1i + 0 + -1zI + z2 = 2 + z
-1i + -1zI + z2 = 2 + z

Add 'zI' to each side of the equation.
-1i + -1zI + zI + z2 = 2 + z + zI

Combine like terms: -1zI + zI = 0
-1i + 0 + z2 = 2 + z + zI
-1i + z2 = 2 + z + zI

Add '-1z2' to each side of the equation.
-1i + z2 + -1z2 = 2 + z + zI + -1z2

Combine like terms: z2 + -1z2 = 0
-1i + 0 = 2 + z + zI + -1z2
-1i = 2 + z + zI + -1z2

Divide each side by '-1'.
i = -2 + -1z + -1zI + z2

Simplifying
i = -2 + -1z + -1zI + z2
