Answer 1

Answer:

4))Let the number be x and y. Then according to the given statement,

x−y=5—(i)

And xy=84—(ii)

From equation (i), we have

x=5+y—(iii)

Putting value from equation (iii) into equation (ii), we have

(5+y)y=84

5y+y2=84

y2+5y−84=0

y(y−8)+4(y−8)=0

(y−8)(y+4)=0

y−8=0 and y+4=0

y=8 and y=−4 as we are talking about positive number therefore

y=8—(iv)

Putting this value from equation (iv) in equation (i), we have

x−8=4

x=4+8

x=12

Hence, from equation (iv) and (v), the two positive numbers
