Question

F the difference of two numbers is 8 and the difference of their squares is 160, then the numbers are:

Answer 1

Answer:

14 , 6

Step-by-step explanation:

Numbers are x ,y

x² - y ² = 160

x -y = 8

x + y = 20

x = 14 , y = 6

Answer 2

Answer:

let first no. be a and second no. be b

then, (a-b)=8...................(i)

(a^2-b^2)=160

(a+b)(a-b)=160

(a+b)*8=160

(a+b)=20...................(ii)

adding eq.(i) and (ii) we get

2a=28 , a=14

substituting a=14 in eq (i), we get b=6
