Answer:
9n+8=420
Explanation:
so 422 people were on busses because 8 went by car so we subtract them from the total. now we divide this number by 9 to find n, or the total number of people on each of the 9 busses. so the equation would look like:
9n+8=430
(and we cant solve it because you cant have like 8 /9 of someone because, well that is murder and you just cant do that....)(math problems are weird)
