A=a+b+c+d/4
subtract a from both sides
0=b+c+d/4
Subtract b from both sides
-b=c+d/4
Finally subtract d/4 from both sides
c=-d/4-b
        
             
        
        
        
Answer:
88 adult tickets were sold
Step-by-step explanation:
3s + 7a = 1102
(s + a = 250)-3
    3s + 7a = 1102
+ -3s - 3a = -750      Add these equations together
4a = 352                  Divide both sides by 4
a = 88
Now plug this into the second equation
s + a = 250
s + 88 = 250 
   - 88     - 88        Subtract 88 from both sides
s = 162
