Question 1059111
Let x represent the first of the three numbers.


The next two consecutive numbers (assumed to be integers) are x + 1 and x + 2.


Since "three times the first number is equal to the sum of the other two", you can write:


3x = (x + 1) + (x + 2)


3x = 2x + 3


3x - 2x = 3


x = 3


The three numbers are then:


x = 3


x + 1 = 3 + 1 = 4


x + 2 = 3 + 2 = 5


Solution: The numbers are 3, 4, and 5.
