Question :
The sum of two numbers is 59 and the difference is 13. What are you numbers ?
Given :
- Difference of these numbers = 13
To Find :
We have to find the numbers .
Concept :
The concept of this question belongs to equations . We have to find the numbers by making equation . So we must have study of creating equations .
To Assume :
In this question we have to assume both the numbers . So ,
So let's get started with solution :
According to question of sum of two no. is 59 . Therefore ,
- x + y = 59 --------------- ( Equation 1 )
According to question difference of these numbers is 13 . So ,
- x - y = 13 --------------- ( Equation 2 )
Now adding both equation :
- x + y + ( x - y ) = 59 + 13
Now , putting value of x in equation 1 to get value of y :
Hence ,
Verification :
We are verifying our answer by putting values of x and y in equation 1 and equation 2 . So ,
For equation 1 :
For equation 2 :
Therefore, we can say that our value for x and y are correct .
