That two numbers.
Let a and b are two numbers -
Then,
a + b = 17 ------(i)
a - b = 3 --------(ii)
Now equation (i) + (ii)
a + b = 17 ------(i)
a - b = 3 --------(ii)
___________________
2a = 20
a = 20/2
Now put the value of a into equation (i) -
a + b = 17
10 + b = 17
b = 17 - 10
Hence ,
- The numbers are 10 and 7.
