Answer:
d = 3 c= 1/4
Step-by-step explanation:
Eq. 1) -4c + 5d = 14
Eq. 2) -4c + 3d = 8 ( the written Eq. says 40 but I am guessing it's 4c )
subtract Eq. 1 and Eq. 2
2d=6
d=3
plug 3 in for d in Eq. 1
-4c + 5(3) = 14
-4c + 15 = 14
-4c = -1
c = 1/4

Answer:
−5+11i
Step-by-step explanation:
(3+6i)−(8−5i)
Subtract 8−5i from 3+6i by subtracting the corresponding real and imaginary parts.
3−8+(6−(−5))i
Subtract 8 from 3. Subtract −5 from 6.
−5+11i
