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:
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
