The sum of three numbers in order is 57. The equation that represents this is x + (x + 1) + (x + 2) = 57. Which value of x from the set {16, 17, 18, 19} makes the equation true?

18

Step-by-step explanation:

x + (x + 1) + (x + 2) = 57

x + x + 1 + x + 2 = 57

x + x + x + 1 + 2 = 57

3x + 3 = 57

3x = 57 - 3

3x = 54

x = 54/3

x = 18

do you have the measurements?
