X + (7 - 3i) + (5 + 9i) + 13i = 10 - 5i

Subtract 13i from both sides

x + (7 -3i) + (5 + 9i) = 10 - 18i

Subtract (5 + 9i). MAKE SURE YOU SUBTRACT 9i TOO. In other words, distribute the negative and subtract 5 and 9i at the same time.

x + (7 - 3i) = 5 - 27i

Do the same with (7 - 3i). You'll be adding 3i since -(-3i) = 3i.

x = -2 - 24i

Answer:

the missing term is (-2-24i)

Step-by-step explanation:

Let

(x+yi)------> the missing term

we have

(x+yi)+(7-3i)+(5+9i)+13i=10-5i

Combine like terms in the left side

(x+7+5)+(yi-3i+9i+13i)=10-5i

(x+12)+(yi+19i)=10-5i

Solve the system of equations

x+12=10 ------> equation A

x=10-12=-2

yi+19i=-5i ------> equation B

yi=-5i-19i=-24i

the missing term is (-2-24i)
