$-1 -i$

Given: $(9 - 7i) - (10 - 6i)$

Add/subtract like terms:

$(9 - 7i) - (10 - 6i) = (9 - 10) + (-7i - (-6i))$

$= -1 -7i + 6i = -1 -i$

Answer 2 · 2018-07-13T20:58:37

$-1-i$

$(9-7i)-(10-6i)$

$=9-7i-10+6i$

$=-1-i$

Answer 3 · 2018-07-13T21:28:01

$-1-i$

Let's distribute the negative sign to the second set of parenthesis to get

$9-7i-10+6i$

The good thing is that, for the most part we can treat the imaginary unit like variables. We combine the corresponding parts to get

$-1-i$

Hope this helps!
