Question

The Difference between two number in 3 and the difference of their square is 54 find the numbers

Answer 1

Answer:

x=10.5 and y=7.5

Step-by-step explanation:

since,x-y=3 (eq.1)

and,x^2-y^2=54(eq. 2)

so,from eq. 1 and 2

(x-y)(x+y)=54

x+y=54/3=18

so,x=18-y

on putting this value in eq.1

18-y-y=3

-2y= -15

y=7.5

so,x=10.5
