Respuesta :

Answer:

The three numbers are 71, 284, 171

Explanation:

Let n = the first number

4n = Second number

100 + n = Third number

Equation :

n + 4n + 100 + n = 526              Combine liked terms

6n + 100 = 526

     - 100   - 100                          Subtract 100 from both sides

6n = 426

÷ 6    ÷ 6                                     Divide 6 from both sides

n = 71

Plug in :

4(71) = 284

100 + 71 = 171
