Answer:
x= -8 , y = 5
x= 25/4 , y = 1/4
Step-by-step explanation:
substitute first eqn into the second eqn:
(7 - 3y)^2 -y^2 = 39
49 - 42y + 9y^2 - y^2 = 39
8y^2 - 42y +10 =0
4y^2 - 21y + 5 = 0
(4y-1) (y-5) = 0
y= 1/4 , 5
when y=1/4
x = 7- 3/4
=25/4
when y= 5
x = 7- 15
= -8

Answer: Rs. 100
Step-by-step explanation:
Given the following :
Total expenditure for dance show = Rs. 25000
Profit made except expenditure = Rs. 12,000
Number of people who observed and paid for the show = 370
Amount paid per person will be :
(Total amount or revenue realized / number of observers who paid)
Total revenue realized = (total expenditure + profit made)
Total Revenue realized = Rs.(25,000 + 12,000) = Rs. 37,000
Amount paid per observer = (Rs. 37,000 / 370)
= Rs. 100
