Question

if (1-i)x + (1+i)y =1-3i ,then (x,y) is equal to

Answer 1

Answer:

(x,y) = (2,-1)

Step-by-step explanation:

First, open the brackets and you get,

x-ix+y+iy=1-3i

Now group the real part together and the imaginary part together.

x+y -i(x-y) = 1-3i

Now equate the real part and imaginary part respectively.

x+y=1 - 1st equation

-i(x-y)=-3i

x-y= 3 - 2nd equation

Now equate 1 and 2 together

Therefore, u get x as 2 and y as -1.
