We can simply add the expression to simplify the expression. So,
(7+3i)+(-8+9i) =7 +3i -8+9i Get rid of paranthesis.
=(7-8)+(3i+9i) Group the like terms.
= -1 + 12i

I don't know what is this
Answer:
f=1
Step-by-step explanation:
Let start off with doing -f plus 4f which gives you 3f. The equation would now be 2+3f=8-3f. Add 3f so you can cancel out the -3f and add the 3f to the other 3f. Now your equation is 2+6f=8. Cancel out do by doing -2. (Don't forget to to it to the 8 also.) Now your equation is 6f=6. Divide 6 from both sides to get 1. (You divide because you want to get f alone.
