Solving
5i2 + -1i2x + -5x2 + x3 = 0

Solving for variable 'i'.

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

Add '5x2' to each side of the equation.
5i2 + -1i2x + -5x2 + 5x2 + x3 = 0 + 5x2

Combine like terms: -5x2 + 5x2 = 0
5i2 + -1i2x + 0 + x3 = 0 + 5x2
5i2 + -1i2x + x3 = 0 + 5x2
Remove the zero:
5i2 + -1i2x + x3 = 5x2

Add '-1x3' to each side of the equation.
5i2 + -1i2x + x3 + -1x3 = 5x2 + -1x3

Combine like terms: x3 + -1x3 = 0
5i2 + -1i2x + 0 = 5x2 + -1x3
5i2 + -1i2x = 5x2 + -1x3

Reorder the terms:
5i2 + -1i2x + -5x2 + x3 = 5x2 + -5x2 + -1x3 + x3

Combine like terms: 5x2 + -5x2 = 0
5i2 + -1i2x + -5x2 + x3 = 0 + -1x3 + x3
5i2 + -1i2x + -5x2 + x3 = -1x3 + x3

Combine like terms: -1x3 + x3 = 0
5i2 + -1i2x + -5x2 + x3 = 0
