Find the sum of 5-9i and - 4+7i, subtract 14-3i

-13 - i

Step-by-step explanation:

The first step is to find the sum

5-9i and - 4+7i

Add the real parts and then the imaginary parts

5+-4 = 1

-9i + 7i = - 2i

5-9i + - 4+7i = 1 - 2i

Now we subtract 14 - 3i

1 - 2i - (14 - 3i)

Subtract the real parts and then the imaginary parts

1-14 = - 13

-2i - - 3i = - 2i+3i = i

1 - 2i - (14 - 3i) = - 13 - i
