Answer 1

Answer:

Step-by-step explanation:

Givens

Let the least number = x

Let the largest number = 2x

Let the second number = x + 3

The sum = 75

Equation

x + 2x + x + 3 = 75                    Combine the terms on the left

Solution

4x + 3 = 75                               Subtract 3 from both sides

4x +3-3= 75-3

4x = 72                                      Divide by 4

4x/4 = 72/4

x = 18

Answer

Smallest number = 18

Second number = 18 + 3 = 21

Largest number = 2*18 = 36

Sum  =                               75
