Question

addition of two consecutive numbers is 13. write an equation​

Answer 1

Answer:

x + (x + 1) = 13

Step-by-step explanation:

x and (x + 1) are 2 consecutive numbers.

Solve:

x + (x + 1) = 13

⇒ x + x + 1 =13

⇒ 2x = 13 - 1

⇒ x = 12/2

⇒ x = 6

∴ the numbers are = x = 6

x + 1 = 6 + 1 = 7

Answer 2

Answer:

6 and 7

Step-by-step explanation:

Let the two consecutive numbers be a and (a+1)

sum of two consecutive numbers = a + a + 1 = 13

⇒ 2a + 1 = 13

⇒ 2a = 13-1

⇒ 2a = 12

⇒ a = 12/2

⇒ a = 6

the two numbers are a and a+ 1

= 6 and 6+1

= 6 and 7
