Question

Find two numbers whose sum is 18 and sum of their reciprocal is 25.
Plz. Give solution stepwise

​

Answer 1

Step-by-step explanation:

let x and y be the two numbers.

x+y = 18

x = 18-y

1/x + 1/y = 1/25

(x+y)/xy = 1/25

18/xy = 1/25

xy = 18*25

xy = 450

(18-y) y = 450

18y - y^2 = 450

y^2-18y+450 = 0

solve it to get required values of x and y
