Answer:
(  , 3 )
, 3 )
Step-by-step explanation:
Given the 2 equations
y = 9x → (1)
6x - y = - 1 → (2)
Substitute y = 9x into (2)
6x - 9x = - 1, that is
- 3x = - 1 ( divide both sides by - 3 )
x = 
Substitute x =  into (1) for corresponding value of y
 into (1) for corresponding value of y
y = 9 ×  = 3
 = 3
Solution is (  , 3 )
, 3 )

Answer:
8-3i
Step-by-step explanation:
The complex additive inverse is the number we need to add so that we get zero.  It is the negative of the number.
 a + bi is –(a + bi) = –a – bi.
a+bi + (-a+-bi) = a-a + bi-bi = 0
The complex additive invers of -8+3i is
-(-8+3i)
Distribute the negative
8 -3i
