Question

If the sum of 2 numbers is 39 and their difference is 15,then find the numbers.​

Answer 1

Answer:

let the two numbers be x, y

x+y=39

x-y=15

solving the equation

2x=54

x=27

y=39-27=12

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Given that,

Sum of 2 no.=39

Difference of them =15

let the no. be x

And second no. Y

So according to first criteria

x+y=39 ----a

And according to second criteria

x-y=15 ----b

Now putting eq b in eq a, we get

x+y=39

x-y=15

--------------

2y=24

y=12

now we will put the value of y in eq a

By doing it we get

x+12=39

x=39-12

x=27

Values are 12 and 27
