S=a-63
s+a=487, using s from above in this equation you get:
a-63+a=487 combining like terms
2a-63=487 adding 63 to both sides
2a=550 dividing both sides by 2
a=275
So there were 275 adult tickets sold.

Answer:
x=-36
Step-by-step explanation:
Add the 7/2x +1/2x to be 8/2x which means that it'll be 4x=18=9/2
then subtract 9/2x on both sides so itll be

-9/2x -9/2x
because if you do 8/2-9/2 it's -1/2
then multiply the reciprocal to both sides so

which then cancels out -1/2 and makes it
x=-36
