8v + 8b = 240
4v + 1b = 54

8v + 8b = 240
-2(4v + 1b = 54)

8v + 8b = 240
-8v - 2b = -108
-----------------------
6b = 132

b = 22
v = 8

4) The senior classes at highschool A and highschool B planned separate trips to New York City. the senior class at the highschool A rented and filled 1 van and 6 buses with 372 students. highschool B rented and filled 4 vans and 12 buses with 780 students. each van and each bus carried the same number of students. How many students can a van carry? how many students can a bus carry?

1v + 6b = 372
4v + 12b = 780

4v + 12b = 780

-4v - 24b = -1488
4v + 12b = 780
--------------------------
-12b = -708

b = 59
v = 18

There were 59 per bus and 18 per van.<==ANSWER

3S + 9C = 75
8S + 5C = 67

-5(3S + 9C = 75)
9(8S + 5C = 67)

-15S - 45C = -375
72S + 45C = 603
----------------------------
57S = 228
