Answer:
10 or x=10
Step-by-step explanation:
First we can combine like-terms.
8x+6=86
Then subtract 6 from both sides
8x=80
Divide by 8
x=10

Regal theater sold 321 adult tickets and 227 children tickets.
Step-by-step explanation:
Given,
Cost of each adult ticket = $6.50
Cost of each child's ticket = $3.50
Total tickets sold = 548
Total worth of sold tickets = $2881
Let,
x represent the number of adult tickets sold
y represent the number of child tickets sold
According to given statement;
x+y=548 Eqn 1
6.50x+3.50y=2881 Eqn 2
Multiplying Eqn 1 by 6.50
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 3
Putting y=227 in Eqn 1
Regal theater sold 321 adult tickets and 227 children tickets.
