Question

(1-3i)x+(2+5i)y=7+i find x&y​

Answer 1

Answer:

This is the solution.......

Answer 2

Answer:

x =3 and y = 2

Step-by-step explanation:

We have-

(1 - 3i)x + (2 + 5i)y = 7 + i

x - 3xi + 2y + 5yi = 7 + i

(x+2y) + (-3x+5y) = 7 + i

Comparing real and imaginary parts, we get-

x + 2y = 7             ---------------------------  1

-3x + 5y = 1          ----------------------------  2

Multiply in equation 1 by 3

3x + 6y = 21

-3x + 5y = 1

Adding both, we have-

11y = 22

y = 2

Put y = 2 in equation 1

x + 2y = 7

x + 2(2) = 7

x + 4 = 7

x = 3
