Answer:

Step-by-step explanation:

let the number be x

then the other number will be( x+7)or(x-7)

you can take any one of the number

xsquare =77+(x+7)square

then you will get the value of x

hence you got the answer

Answer 2

let one number be x

other no =x+7

(x+7)² -77 =x²

x²+49+14x-77=x²

x²-28+14x=x²

x²-x²+14x = 28

14x= 28

x= 2

other no = x+7 =2+7 =9

the numbers are 2 and 9
