    Answer: 1+3i

    Step-by-step explanation:

    (6 + 4i) - (5 + i)

    Before solving further, note that:

    Minus * Minus = Plus

    Plus * Minus = Minus

    Plus * Plus = Plus

    (6 + 4i) - (5 + i)

    Open the bracket

    = 6 + 4i - 5 - i

    Collect like terms

    = 6 - 5 + 4i - I

    = 1 + 3i
