Answer 5

First simplify \(\Large{4i(-3-yi)}\) I belive that when multiplying \(\Large{4i}\) to \(\Large{yi}\) the \(\Large{i}\) will cancel out....

Answer 6

Alright.

Answer 7

hint:
if we apply the distributive property of multiplication at the left side, we get:
\[ \huge - 12i - 4y{i^2} + 7 = 27 - 12i\]

Answer 8

furthermore, by definition of the imaginary unit, we can write this:
\[\huge {i^2} = - 1\]
