    Hey there!

    Answer:\boxed{-49-4i}

    Explanation:

    (2 - 61) - (-10 + 4i)

    First, you need to open the parentheses. Notice how there is a subtraction sign before the second parentheses. You will need to multiply everything in the second parentheses by -1.

    2-61+10-4i

    -10 \times -1 = 10 because when two negative numbers are multiplied, the product will be positive.

    Now you need to combine like-terms.

    2-61+10 \ | 4i\\2-61=-59 \text{ and} -59+10=-49

    You will be left with -49 and 4i. The last step is to add them.

    -49 \text{ and } 4i \rightarrow -49+4i\\-49-4i

    \boxed{-49-4i}\text{ is your answer.}

    Hope this helps!
