When the smaller of two consecutive integers is added to three times the larger, the result is 31. Find the integers.

Asked by Silvarion10

Answer (2)

Let x be the smaller number and y the larger:
As the numbers are consecutive y - x = 1 And 3y + x = 31 (3 times the large added to the smaller)
From the first equation y = x + 1 By substituting: 3(x + 1) + x = 31 3x + 3 + x = 31 4x = 28 x = 7
y = x + 1 y = 7 + 1 = 8

The two consecutive integers are 7 and 8. When the smaller integer, 7, is added to three times the larger integer, 24 (3 times 8), the total is 31. This satisfies the conditions of the problem.
