If the sum of three consecutive numbers is 36. Find the numbers.

aleksandrvk [35]

Answer:

11, 12, 13

Step-by-step explanation:

x is the first number

(x + 1) is the second number

(x + 2) is the third number

x + x+1 + x+2 = 36

3x + 3 = 36

3x = 36 - 3

3x = 33

x = 11 ← the first number

the second number = x + 1 = 11 + 1 = 12

the third number = x + 2 = 11 + 2 = 13
