The sum of three numbers is 123. The third number is 4 times the first. The second number is 9 more than the first. What are the numbers? First number:

Second number:

Third number:

Step-by-step explanation:

Let the first number = x

Let the second number = x + 9

Let the third number = 4x

Together they make 123

x + x + 9 + 4x = 123              combine the left

6x + 9 = 123                         Subtract 9 from both sides

6x = 123 - 9

6x = 114                                 Divide by 6

x = 114/6

x = 19

First number = 19

Second number = 19 + 9 = 28

Third number = 4*19 = 76
