Answer:
200 seats
Step-by-step explanation:
Let s = numbers of seats
1/5s = children
3/4 s = adults
10 = empty
The total number of seats = children + adults + empty
s = 1/5s + 3/4s + 10
Subtract 1/5s and 3/4s from each side
s -1/5s -3/4s= 1/5s-1/5s + 3/4s-3/4s + 10
s - 1/5s - 3/4s = 10
Get a common denominator
20s/20 - 4s/20 -15s/20 = 10
Combine like terms
1s/20 = 10
Multiply each side by 20
s/20 *20 = 20*10
s = 200
