​

Answer 1

Hey mate❤

given here

sum of two number = 12

so,

let x and y are two number

so,

x+y= 12. ...(1)

Again ,

different of there square = 12

so,

x²-y²=12 ...(2)

or,

(x+y)(x-y)=12

by (1) ,

x-y= 12/12

x-y= 1. ....(3)

equation (1)+(3)

we get

2x= 13

x= 13/2

by (3),

13/2 - y =1

y= 13/2 -1

y= (13-2)/2

y= 11/2

_______________________

Thus:--

value of

x= 13/2

y= 11/2
