(I can't see the answer for number 10... it would be good if you told me the question)
Answer:
y = 
Step-by-step explanation:
Given
5x - 8y = 11 ( subtract 5x from both sides )
- 8y = 11 - 5x ( multiply through by - 1 )
8y = - 11 + 5x = 5x - 11 ( divide both sides by 8 )
y = 
A
This is like a base form of a prime polynomial
X^2+x+1
3n+2n= 5n
22+38=60
180-60=60
60=5n
n=12
