Question

if 3 X + y i is equal to 7 and X + 3 y is equal to 13 find the value of x and y​

Answer 1

Step-by-step explanation:

Find x & y if

3+i

x−1

+

3−i

y−1

=i

(3)

2

−(i)

2

(x−1)(3−i)+(y−1)(3+i)

=i

9+1

3x+1−xi−3+3y+yi−3−i

=i

3x−6+3y(y−x−10)i

3x−6+3y+(y−x)i

=10i

separating real & imagery part,

we get ,

3x−6+3y=0

3x+3y=6

x+y=2....(1)

y−x−10=0

x−y=−10....(2)

(1)+(2)

2x=−8

x=−4,y=6sd
