Answer:
2(x + 32)
Step-by-step explanation:
Let "a number" = x
Note "the sum (addition) of a number and thirty-two" = x + 32
"Twice (of the above)" (multiplication) = 2(x + 32)
2(x + 32) is your answer.

To find the answer, set up a system of equations.
Let x=adult tickets and y=senior citizen tickets.
x+y=556
22x+12y=8492
Change the first equation to make it easy to combine with the second equation.
y=556-x
Now substitute (556-x) for y in the second equation.
22x+12(556-x)=8492
Simplify and combine like terms.
22x+6672-12x=8492
10x=1820
x=182
182 adult tickets were sold, so to solve for the number of senior citizen tickets sold, subtract 182 from 556.
556-182=374
374 senior citizen tickets were sold.
