Well, first write all of the terms without parentheses:
7 + 15i - 14 + i
(That last term is positive because subtracting a negative i is the same as adding it.)
then, combine like terms:
(7 - 14) + (15i + i)
Do some simple addition/subtraction:
-7 + 16i
And you're done! As long as you keep your signs correct, this'll become easy for you.

Add the real parts together and the imaginary parts together:
(7 - 14) + (15 + 1)i = -7 + 16i
