As given
The school that Jack goes to is selling tickets to a choral performance.
On the first day of ticket sales the school sold 9 senior citizen tickets and 8 student tickets for a total of $156.
Equtaions becomes
9x + 8y = 156
As given
The school took in $163 on the second day by selling 7 senior citizen tickets and 9 student tickets.
Equations becomes
7x + 9y = 163
Multipy 9x + 8y = 156 by 9 .
81x + 72y = 1404
Multiply 7x + 9y = 163 by 8 .
56x + 72y = 1304
Subtracted 56x + 72y = 1304 from 81x + 72y = 1404 .
81x - 56x + 72y - 72y = 1404 - 1304
25x = 100

x = $ 4
Putting value of x in the 56x + 72y = 1304 .
56 × 4 + 72y = 1304
224 + 72y = 1304
72y = 1304 - 224
72y = 1080

y = $15
Therefore the price of a senior citizen ticket is $4 and price of a student ticket is $15 .
Answer:

Answer:
2
Step-by-step explanation:
You count terms that are seperated by - and + signs. Any type of fraction is considered one term.
So you count 8y as one term and the rest is a whole fraction so you also count that as one term.
You add all the terms together and you have 2 terms in this equation.
Hope this helped :)
