Answer: 3 & 18
Step-by-step explanation:
x+6x = 21
7x=21
x=21/7
x= 3
21-3 = 18
so 3 and 18
Answer:
no

As given
The local amusement park is a popular field trip destination.
This year the senior class at High School A and the senior class at High School B both planned trips there.
The senior class at High School A rented and filled 6 vans and 10 buses with 376 students.
Equations becomes
6x + 10y = 376
As given
High School B rented and filled 3 vans and 2 buses with 104 students.
Equations becomes
3x + 2y = 104
Multiply 3x + 2y = 104 by 2 and subtracted from 6x + 10y = 376 .
6x - 6x + 10y - 4y = 376 - 208
6y = 168
![y = \frac{168}{6}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B168%7D%7B6%7D)
y = 28
Putting the value of y in the equation 3x + 2y = 104 .
3x + 28 × 2 = 104
3x + 56 = 104
3x = 104 - 56
3x = 48
![x = \frac{48}{3}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B48%7D%7B3%7D)
x = 16
Therefore the number of students can a van carry are 16 and number of students can a bus carry are 28 .
