Question

The sun of the no.s is 55 and difference is 25 what are the no.s

Answer 1

Step-by-step explanation:

let one no. be x and other be y

then,

x+y=55 -------1

x-y=25 --------2

now add 1 and 2

we get

2x=80

therefore, x=40

now y =?

substitute in equation 1

40+y=55

therefore,

y=15.

hope it helps u

Answer 2

Step-by-step explanation:

Let the two numbers ba "x" and "y" whose

sum=55 and difference=25

x+y=55

y=55-x

By putting the value of x in this equation.

x-y=25

x-(55-x)=25

x+55+x=25

2x=25-55

2x=-30

x=-15

Now putting the value of x in x-y=25

-15-y=25

y=-15-25

y=-40

The number whose sum is 55 and difference is 25 are -15 and -40
