    Find the real numbers x and y such that:
    (1+i)x + (2-3i)y = 10

    Equate real parts:

    x + 2y = 10. (1)

    Equate imaginary parts:

    x – 3y = 0. (2)

    Solving simultaneously yields x = 6 and y = 2.

    Another slightly different method is to multiply the original equation by (1-i) then equation only the imaginary parts yields:

    and
    equating the real part of the original part shows
