Answer:

Smallest number = 15

Second number = 177

Third number = 109

Explanation:

Givens

Let the first number = x

Let the second number = 12x - 3

Let the third number = 7x + 4

Equation

x + 12x - 3 + 7x +4 = 301 Combine like terms

Solution

20x + 1 = 301 Subtract 1 from both sides

20x = 301 - 1 Combine

20x = 300 Divide by 20

x = 300/20

x = 15
