Answer:
Step-by-step explanation:
Start with:
Distribute the 
into 
:
Combine like terms:
Add to both sides of the equation:
Subtract 
from both sides of the equation:
Divide both sides of the equation by the coefficient of 
, which is 
:
or
X=amount of children tickes sold
y=amount of adult tickets sold
2 times of children as adult
x=2y
total cost is 800
5x+10y=800
divide both sides by 5
x+2y=160
x=2y
2y+2y=160
4y=160
divie by 4
y=40
x=2y
x=2(40)
x=80
80 children tickets
40 adult tickets
