Add the real and the imaginary parts separately.
(1+7i)-(3+2i)
= (1 - 3) + i(7 - 2)
= -2 - 5i.

(1 + 7i) - (3 + 2i) = 1 + 7i - 3 - 2i
1 + 7i - 3 - 2i = -2 + 5i
answer = -2 + 5i

First expand the - through the second part
1 + 7i -3 - 2i
Then just add the real and imaginary parts separately to get
-2 + 5i
