Answer:
30 seats
Step-by-step explanation:
To answer this question, we will be assigning values for both rows and seats.
R = Rows
S = Seats
Remember that rs = 600
r = s - 10, plug this equation into rs = 600, and factor it:
s(s-10) = 600
s^2-10s-600 = 0
(x-30)(x+20) = 0
There are 30 seats in the row. To determine which one is your answer, your answer MUST be positive because it is impossible to have negative seats. (x-30) is 30, which is the positive value found when factoring.

Answer:
x=31
y=15
Step-by-step explanation:
let x and y be the 2 part
x+y=46
x-2y=1 ⇒ x=1+2y
substitute :
1+2y+y=46
3y=46-1
3y=45 ⇒ y=45/3=15
x-2y=1
x-2(15)=1 ⇒ x=1+30 ⇒x=31
x= 2 times y(15)+1
y=15
31+15=46
