Combining like terms refers to adding all of the terms that have a exponent or a variable in an expression.
Example: 6y + 10y - 2
You would combine the like terms, which two numbers have a variable.
6y + 10y = 16y
After combing the like terms, the new expression should be:
16y - 2

Answer:
612 adults
361 students
Step-by-step explanation:
To solve this question, set two equations:
Let x be number of adults and y be number of students.
As there are in total 937 people, the equation would be the sum of both adults and children:
![x+y=937](https://tex.z-dn.net/?f=x%2By%3D937)
...... ( 1 )
As the total sale amount is $1109, the equation would be to add up the ticket fee:
...... ( 2 )
Put ( 1 ) into ( 2 ):
![2(937-y)+0.75y=1,109](https://tex.z-dn.net/?f=2%28937-y%29%2B0.75y%3D1%2C109)
![1874-2y+0.75y=1,109](https://tex.z-dn.net/?f=1874-2y%2B0.75y%3D1%2C109)
![-1.25y=-765](https://tex.z-dn.net/?f=-1.25y%3D-765)
![y=763/1.25](https://tex.z-dn.net/?f=y%3D763%2F1.25)
![y=612](https://tex.z-dn.net/?f=y%3D612)
Put y into ( 1 ):
![x=973-612](https://tex.z-dn.net/?f=x%3D973-612)
![x=361](https://tex.z-dn.net/?f=x%3D361)
Therefore there are 612 adults and 361 students.
