Find the values of x and y in the following equation. (x+yi)+(4+9i)=9-4i a. x = -9 and y = 4 b. x = 5 and y = -13 c. x = 5 and y = 13 d. x = 9 and y = -4

B. x = 5 and y = -13

Step-by-step explanation:

Subtract the constant on the left:

... (x +yi) = (9 -4i) -(4 +9i)

... = (9 -4 +i(-4-9))

... = 5 -13i

Matching real and imaginary parts, we see that ...

... x = 5, y = -13
