Solving
-12i2 + -4i2x + 3x2 + x3 = 0

Solving for variable 'i'.

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

Add '-3x2' to each side of the equation.
-12i2 + -4i2x + 3x2 + -3x2 + x3 = 0 + -3x2

Combine like terms: 3x2 + -3x2 = 0
-12i2 + -4i2x + 0 + x3 = 0 + -3x2
-12i2 + -4i2x + x3 = 0 + -3x2
Remove the zero:
-12i2 + -4i2x + x3 = -3x2

Add '-1x3' to each side of the equation.
-12i2 + -4i2x + x3 + -1x3 = -3x2 + -1x3

Combine like terms: x3 + -1x3 = 0
-12i2 + -4i2x + 0 = -3x2 + -1x3
-12i2 + -4i2x = -3x2 + -1x3
