उत्तर

(4 − 5i)x + (2 + 3i)y = 10 − 7i

∴ (4x + 2y) + (3y − 5x) i = 10 − 7i

Equating real and imaginary parts, we get

4x + 2y = 10

i.e., 2x + y = 5  ...(i)

and 3y − 5x = −7  ...(ii)

Equation (i) x 3 − equation (ii) gives

11x = 22

∴ x = 2

Putting x = 2 in (i), we get

2(2) + y = 5

∴ y = 1

∴ x = 2 and y = 1
