1. Problem Description

We are given the equation
x1+iy2+i=15i32i\frac{x}{1+i} - \frac{y}{2+i} = \frac{1-5i}{3-2i}
We are asked to solve this equation. It is assumed that we are looking for real numbers xx and yy that satisfy the given equation.

2. Solution Steps

First, we multiply both sides of the equation by (1+i)(2+i)(32i)(1+i)(2+i)(3-2i) to get rid of the denominators:
x(2+i)(32i)y(1+i)(32i)=(15i)(1+i)(2+i)x(2+i)(3-2i) - y(1+i)(3-2i) = (1-5i)(1+i)(2+i)
Let's expand the terms:
(2+i)(32i)=64i+3i2i2=6i+2=8i(2+i)(3-2i) = 6 - 4i + 3i - 2i^2 = 6 - i + 2 = 8-i
(1+i)(32i)=32i+3i2i2=3+i+2=5+i(1+i)(3-2i) = 3 - 2i + 3i - 2i^2 = 3 + i + 2 = 5+i
(15i)(1+i)=1+i5i5i2=14i+5=64i(1-5i)(1+i) = 1 + i - 5i - 5i^2 = 1 - 4i + 5 = 6 - 4i
(64i)(2+i)=12+6i8i4i2=122i+4=162i(6-4i)(2+i) = 12 + 6i - 8i - 4i^2 = 12 - 2i + 4 = 16-2i
So our equation becomes:
x(8i)y(5+i)=162ix(8-i) - y(5+i) = 16-2i
8xix5yiy=162i8x - ix - 5y - iy = 16 - 2i
(8x5y)i(x+y)=162i(8x - 5y) - i(x+y) = 16 - 2i
Equating real and imaginary parts, we have the system of equations:
8x5y=168x - 5y = 16
x+y=2x+y = 2
From the second equation, y=2xy = 2-x. Substituting into the first equation:
8x5(2x)=168x - 5(2-x) = 16
8x10+5x=168x - 10 + 5x = 16
13x=2613x = 26
x=2x=2
Then y=2x=22=0y = 2-x = 2-2 = 0

3. Final Answer

x=2x=2, y=0y=0
