Example 1 - Chapter 5 Class 11 Complex Numbers - NCERT If 4x + i(3x โ€“ y) = 3 + i (โ€“ 6), where x and y are real numbers, then find the values of x and y. Here 4x + i (3x โ€“ y) = 3 + i (โ€“6) Equating the real and the imaginary parts Real 4๐‘ฅ = 3 ๐‘ฅ = 3/4 Imaginary 3x โ€“ y = โ€“ 6 3(3/4) โ€“ y = โ€“ 6 9/4 โ€“ y = โ€“ 6 9/4 + 6 = y y = 9/4 + 6 y = (9+6(4))/4 y = (9+ 24)/4 y = 33/4 Hence x = 3/4 & y = 33/4 is the solution of the given equation
