R * s = 273
r = s - 8.....s = r + 8
r(r + 8) = 273
r^2 + 8r = 273
r^2 + 8r - 273 = 0
(r - 13)(r + 21) = 0
r - 13 = 0
r = 13
r + 21 = 0
r = -21.....extraneous solution...not ur answer
r = 13
s = r + 8 = 13 + 8 = 21
so there are 13 rows.....each row containing 21 seats
The another way to represent the same line, for solving 
will be: 
<u><em>Explanation</em></u>
Given equation of the line is: 
"Solving " means <u>we need to get</u> <u>alone in left side.</u> So, we will eliminate all other terms except from the left side.
First we will <u>subtract 2x </u>from both sides. So, we will get......
Now, we will <u>divide both sides by 3</u> for getting alone. So.....
Thus, the another way to represent the same line, for solving will be:
Answer:
A constant
Step-by-step explanation:
Well, ideally I'd like more details, but a number that doesn't change in a mathematical equation is called a constant.
