X=(3+2j)x(4+9j)

Solution for X=(3+2j)x(4+9j) equation:

Simplifying
X = (3 + 2j) * x(4 + 9j)

Reorder the terms for easier multiplication:
X = x(3 + 2j)(4 + 9j)

Multiply (3 + 2j) * (4 + 9j)
X = x(3(4 + 9j) + 2j * (4 + 9j))
X = x((4 * 3 + 9j * 3) + 2j * (4 + 9j))
X = x((12 + 27j) + 2j * (4 + 9j))
X = x(12 + 27j + (4 * 2j + 9j * 2j))
X = x(12 + 27j + (8j + 18j2))

Combine like terms: 27j + 8j = 35j
X = x(12 + 35j + 18j2)
X = (12 * x + 35j * x + 18j2 * x)

Reorder the terms:
X = (35jx + 18j2x + 12x)
X = (35jx + 18j2x + 12x)

Solving
X = 35jx + 18j2x + 12x

Solving for variable 'X'.

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