WebIf x + iy = a + ib then x = a and y = b where a, b, x and y are real numbers. CALCULATION: Given: 4x + i (3x -y) = 3 + i (- 6) As we know that, if x + iy = a + ib then x = a and y = b where a, b, x and y are real numbers. ⇒ 4x = 3 ⇒ x = 3/4 ⇒ 3x - y = - 6 So, substitute x = 3/4 in the above equation we get, ⇒ 9/4 - y = - 6 ⇒ y = (9/4) + 6 = 33/4 Web⇒ \(\rm (x+iy)=a^3 + i3a^2b - 3ab - ib^2\) ⇒ \(\rm (x+iy)=(a^3 - 3ab^2) - i(b^3 -3a^2b)\) Compare the real and imaginary part and equate them, we get. x = a 3 - 3ab 2 and y = - … the now chicago
