Solving Complex Number Equations: (x + yi) + (8 - 5i) = 4 + 3i
This article will guide you through solving the complex number equation (x + yi) + (8 - 5i) = 4 + 3i.
Understanding Complex Numbers
Complex numbers are numbers that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, defined as the square root of -1.
Solving the Equation
-
Combine real and imaginary terms:
-
The real terms are x and 8, while the imaginary terms are yi and -5i.
-
Combine the real terms on one side and the imaginary terms on the other:
(x + 8) + (yi - 5i) = 4 + 3i
-
-
Equate real and imaginary components:
-
Since the equation holds true for all values of x and y, we can equate the real and imaginary components on both sides.
-
This gives us two separate equations:
x + 8 = 4 yi - 5i = 3i
-
-
Solve for x and y:
-
Solve the first equation for x:
x = 4 - 8 = -4
-
Solve the second equation for y:
yi = 3i + 5i = 8i y = 8 (since i cancels out on both sides)
-
Solution
Therefore, the solution to the equation (x + yi) + (8 - 5i) = 4 + 3i is x = -4 and y = 8.
This can be expressed in the complex number form as -4 + 8i.
