## starowl1 Group Title Find the real numbers x and y that make the equation true. 5 + yi = x + 3i 2 years ago 2 years ago

$5 + yi = x + 3i$ $5=x;\qquad y=3$

2. Calcmathlete Group Title

What ^ did is basically bring the x and y terms to one side. $5 + yi = x + 3i$$x - yi = 5 - 3i$Then separate the real and imaginary portions since they cannot mix. $x = 5$$-yi = -3i$$y = 3$
