X=number of students
9x+12x=630
21x=630
x=30
so for high school, a, the 9 vans carried (9*30) 270 students while the 12 buses carried (12*30)=360 students. check:270+360=630
so for high school,b.
1x+6x=252
7x=252
x=<span>36
so the 1 van carries 36 students and the 6 buses carries (6*36) 216 students. check: 216+36=252</span>
