    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
