Given:
Admission to the local movie theater is $3 for each child and $7 for each adult.
A group of 12 people pay $64 admission.
To find:
The number of children in a group.
Solution:
Let the number of children be x and number of adults be y.
According to the question,
Total persons :
...(i)
Total cost :
...(ii)
Multiply equation (i) by 7 and subtract the result from (ii).
![3x+7y-7(x+y)=64-7(12)](https://tex.z-dn.net/?f=3x%2B7y-7%28x%2By%29%3D64-7%2812%29)
![3x+7y-7x-7y=64-84](https://tex.z-dn.net/?f=3x%2B7y-7x-7y%3D64-84)
![-4x=-20](https://tex.z-dn.net/?f=-4x%3D-20)
Divide both sides by -4.
![x=5](https://tex.z-dn.net/?f=x%3D5)
Therefore, the number of children is 5.

Step-by-step explanation:
Let's solve your equation step-by-step.
5x−5
x−2
=
1
3
Step 1: Cross-multiply.
5x−5
x−2
=
1
3
(5x−5)*(3)=1*(x−2)
15x−15=x−2
Step 2: Subtract x from both sides.
15x−15−x=x−2−x
14x−15=−2
Step 3: Add 15 to both sides.
14x−15+15=−2+15
14x=13
Step 4: Divide both sides by 14.
