Question

 If 3x² + y² / 3x² - y² = 73 / 23 , then find the value of x/y .​

Answer 1

Answer:

x/y = 4/5

Step-by-step explanation:

3x^2 + y^2 = 73 ....(1)

3x^2 - y^2 = 23 ....(2)

now subtract equation (2) from equation (1)

then we find

2y^2 = 50

y^2 = 50/2 = 25

then, y = √25 = 5

put the value of in equation (2)

so we find. 3x^2 - 25 = 23

3x^2 = 48

x^2 = 48/3 = 16

x = 4

so the value of x/y = 4/5
