Answer:
- Friday's tickets: $26 each
- Saturday's tickets: $35 each
Step-by-step explanation:
We presume that 4 tickets were bought each day, so the price of 1 ticket is 1/4 of the total price:
   (1/4)($104) = $26
   (1/4)($140) = $35
The cost of each ticket on Friday was $26; on Saturday, the cost was $35.
 
        
             
        
        
        
The second and the third one are similar.

To do this we need to move 10 to other side.  To accomplish this you just need to add 10 to both side since (-10) 
so 
A+ 10 = c -10 + 10 
we get
A+ 10 = c
lets say it wasn't -10 but positive 10. 
A = c + 10  then we would subtract 10 from both sides
A -10 = c + 10 - 10 
we get 
A  - 10 = C
