Question 1059111: Find three consecutive numbers such that three times the first number is equal to the sum of the other two
Answer by solve_for_x(190)   (Show Source):
You can put this solution on YOUR website! 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.
