The sum of a number and another number, which is ten more than the original number is 2(x + 5).
How do we find the sum of a number and another number?
To find the sum of the numbers, we shall use x to represent the original number.
The number which is ten more than the original number = x + 10,
where x = the original number
The sum of the original number and the number that is 10 more than the original number = x + x + 10
If we combine the like terms, we have: 2x + 10
Factoring out a 2, we shall get 2(x + 5).
Hence, the sum of a number and another number that is 10 more than the original number is 2(x + 5).
