15-28i=3l + (4m) i solve ... ?

Simplifying

15 + - 28i = 3l + (4m) * i

Remove parenthesis around (4m)

15 + - 28i = 3l + 4m * i

Multiply m * i

15 + - 28i = 3l + 4im

Reorder the terms:

15 + - 28i = 4im + 3l

Solving

15 + - 28i = 4im + 3l

Solving for variable 'i'.

Move all terms containing i to the left, all other terms to the right. Add '-4im' to each side of the equation.

15 + - 28i + - 4im = 4im + - 4im + 3l

Combine like terms: 4im + - 4im = 0

15 + - 28i + - 4im = 0 + 3l

15 + - 28i + - 4im = 3l

Add '-15' to each side of the equation.

15 + - 28i + - 15 + - 4im = - 15 + 3l

Reorder the terms:

15 + - 15 + - 28i + - 4im = - 15 + 3l

Combine like terms: 15 + - 15 = 0

0 + - 28i + - 4im = - 15 + 3l

-28i + - 4im = - 15 + 3l

Reorder the terms:

15 + - 28i + - 4im + - 3l = - 15 + 3l + 15 + - 3l

Reorder the terms:

15 + - 28i + - 4im + - 3l = - 15 + 15 + 3l + - 3l

Combine like terms: - 15 + 15 = 0

15 + - 28i + - 4im + - 3l = 0 + 3l + - 3l

15 + - 28i + - 4im + - 3l = 3l + - 3l

Combine like terms: 3l + - 3l = 0

15 + - 28i + - 4im + - 3l = 0
