Find the values of x and y in the following equation.

a.
x = 9 and y = -4
b.
x = -9 and y = 4
c.
x = 5 and y = -13
d.
x = 5 and y = 13

The question is incomplete. Here is the complete question:

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 = -9 and y = 4

C.  x = 5 and y = -13

D.  x = 5 and y = 13

C.

Step-by-step explanation:

Given:

The equation is given as:

Let us combine the like terms using the commutative property of addition.

Combine the real parts together and imaginary parts together. This gives,

The left side of the equation is equal to the right side only if the real parts of  both the sides are equal and imaginary parts of both the sides are equal. Therefore,

Therefore, the values of in the given equation is

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
