The sum of 8 and 7 when doubled is 30.

Given that,

  • The first number is 8.
  • And, the second number is 7.
  • Now we have to sum these numbers.

So based on the above information, the sum of the above numbers should be

= 8 + 7

= 30

Therefore we can conclude that the sum of 8 and 7 when doubled is 30.
