Question

The sum of three numbers is 33. The second number is 7 less than the first, and the third is two more than the second. Find the numbers

Answer 1

First number: 15

Second number: 8

Third number: 10

Explanation:

1. The equation is 33 = x + (x - 7) + (x - 7 + 2) .
2. Remove the parenthesis and combine the like terms. 33 = 3x -12
3. Add 12 on both sides. 45 = 3x
4. Divide by 3 on both sides. x = 15
