Explanation:

Givens

Let the first number = x

Let the second number = 2x

Let the third number = x + 100

Total = 468

==============

Solution

x + 2x + x + 100 = 468 Combine the xs

4x + 100 = 468 Subtract 100 from both sides

4x = 468 - 100

4x = 368 Divide by 4

x = 368/4

x = 92

===============

Answer

First number = 92

Second num = 2 * 92= 184

Third number = 92 + 100= 192

Total 468
