The sum of 3 numbers is 34. The first is three less than the second, while the third is 4 more than the

second. Find the numbers.

Let a = first number

Let a + 3 = second number .....................2

Let a + 4 = third number ...............................3

a + a + 3 + a + 4 = 34

3a + 7 = 34

3a = 27

a = 9

Put a in 2 and 3, then

The numbers are {9, 12, 13}
