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
