Solving for variable 'i'.

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

Add '-1' to each side of the equation.
1 + 5i + -2iz + 1z + -1 + z2 = 0 + -1

Reorder the terms:
1 + -1 + 5i + -2iz + 1z + z2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 5i + -2iz + 1z + z2 = 0 + -1
5i + -2iz + 1z + z2 = 0 + -1

Combine like terms: 0 + -1 = -1
5i + -2iz + 1z + z2 = -1

Add '-1z' to each side of the equation.
5i + -2iz + 1z + -1z + z2 = -1 + -1z

Combine like terms: 1z + -1z = 0
5i + -2iz + 0 + z2 = -1 + -1z
5i + -2iz + z2 = -1 + -1z

Add '-1z2' to each side of the equation.
5i + -2iz + z2 + -1z2 = -1 + -1z + -1z2

Combine like terms: z2 + -1z2 = 0
5i + -2iz + 0 = -1 + -1z + -1z2
5i + -2iz = -1 + -1z + -1z2

Reorder the terms:
1 + 5i + -2iz + z + z2 = -1 + -1z + -1z2 + 1 + z + z2

Reorder the terms:
1 + 5i + -2iz + z + z2 = -1 + 1 + -1z + z + -1z2 + z2

Combine like terms: -1 + 1 = 0
1 + 5i + -2iz + z + z2 = 0 + -1z + z + -1z2 + z2
1 + 5i + -2iz + z + z2 = -1z + z + -1z2 + z2

Combine like terms: -1z + z = 0
1 + 5i + -2iz + z + z2 = 0 + -1z2 + z2
1 + 5i + -2iz + z + z2 = -1z2 + z2

Combine like terms: -1z2 + z2 = 0
1 + 5i + -2iz + z + z2 = 0
