%284-7i%29%2F3i=4%2F%283i%29-7cross%28i%29%2F3cross%28i%29Distributive property.
%284-7i%29%2F3i=4%2F%283i%29-7%2F3Simplify.
Looking at i,
i*i=-1
i=-1/i
1/i=-i
Substituting that value,
%284-7i%29%2F3i=4%2F%283i%29-7%2F3
%284-7i%29%2F3i=%284%2F3%29%2A%281%2Fi%29-7%2F3
%284-7i%29%2F3i=4%2F3%2A%28-i%29-7%2F3Substitute.
%284-7i%29%2F3i=-%28%287%2B4i%29%29%2F3Simplify.
