2x + 7 + (3 – yli = -4 + 6
Find the values of x and y that make each equation true.

Step-by-step explanation:

(1) 5 + iy = x + i3 In order for complex numbers to be equal the real parts have to be equal and the imaginary parts have to be equal. For (1) we have (2) 5 = x for the real parts, therefore (3) x = 5 And for the imaginary parts we have (4) iy = i3, therefore (5) y = 3 x = 5 and y = 3.
