One Number Is 10 More Than The Other. It Their Sum Is 52.Find The Number

Given: One number is 10 more than the other and their sum is 52.

To find: We have to find the number.

Solution:

Let the first number be = a

So second number be = a + 10

Now,

=> a + a + 10 = 52

=> 2a + 10 = 52

=> 2a = 52 - 10

=> 2a = 42

$\Longrightarrow \ a\ =\ \frac{42}{2}$

=> a = 21

Therefore,

First number be = a = 21

Second number be = a + 10 = 21 + 10 = 31
