Question

The sum of two natural
numbers
is 25 and their difference is 7 find the numbers​

Answer 1

Answer:

9 and 16

Step-by-step explanation:

do this by trial and error

16+9=25

16-9=7

Answer 2

Answer:

let first natural no. be x

second natural no. be y

then,

x+y=25.........[1.]

'.' x=25-y

case 1] .   if x>y,

               x-y=7............[2.]

by substituting [1.] in [2.]

25-y-y=7

25-2y=7

18=2y

y=9

putting value of y in [1.]

x+9=25

x=16

case 2] if y>x then,

          y-x=7............[3.]

by substituting [1.] in [3.]

y-(25-y)=7

2y-25=7

2y=32

y=16

putting value of y in [1.]

x+16=25

x=9

           

             

Step-by-step explanation:

We just get exchanged values in both the cases so its up to you how briefly you have to write.....

I have used substitution method here....
