The sum of two consecutive numbers is 11. Find the numbers.

Solution

Let the number be x.
Hence, the two consecutive numbers are x and x+1.
According to the given statement, the equation becomes
⇒ x + x + 1 = 11
⇒ 2x + 1 = 11
⇒ 2x = 10
⇒ x = 10/2 = 5
If x = 5, then x + 1 = 5 + 1 = 6
Hence, the two numbers are 5 and 6.
