You can put this solution on YOUR website!
X+(X-59)=691 OR 2X=691+59 OR 2X=750 OR X=750/3 OR X=375 ADULT TICKETS &
375-59=316 OR 316+375=691

Let's assign variables to the different groups so we can later solve this system with either substitution or elimination.
Student tickets = s
adult tickets = a
So, translate the english into math.
Since a total of 691 tickets were sold, we can derive the equation:
s%2Ba=691
Then, there were 59 fewer students sold, that means more adult tickets were sold.
s=a-59
Now put these in a system of equations and solve.
s%2Ba=691
s=a-59
For this system, I would suggest substitution because there is already an isolated variable.
%28a-59%29%2Ba=691
2a-59=691
2a=750
a=375
We now know that highlight%28375%29 adult tickets were sold.
s=375-59
s=316
highlight%28316%29 student tickets were sold.
Hope this helps!
