What is the four-digit number in which the first digit is one-third the second, the third is the sum of the first and second, and the last is three times the second?

1,349

Step-by-step explanation:

Using the verbal descriptions from the problem, we can set up the following expressions for each number:

first: 'one-third the second' =

second: 'x'

third: 'the sum of the first and second' = + x =

fourth: 'three times the second' = 3x

Since the four-digit number has to be whole numbers, the first choice would be the integer '3':

first:

second: x = 3

third:

fourth: 3x = 3(3) = 9

final  1,349
