    Answer:

    1/3=0.333…

    Step-by-step explanation:

    Step by step solution :

    STEP

    1

    :

    Equation at the end of step 1

     3×2 –  x  = 0  

    STEP

    2

    :

    STEP

    3

    :

    Pulling out like terms

    3.1     Pull out like factors :

      3×2 – x  =   x • (3x – 1)  

    Equation at the end of step

    3

    :

     x • (3x – 1)  = 0

    Theory – Roots of a product

    4.1    A product of several terms equals zero.  

    When a product of two or more terms equals zero, then at least one of the terms must be zero.  

    We shall now solve each term = 0 separately  

    In other words, we are going to solve as many equations as there are terms in the product  

    Any solution of term = 0 solves product = 0 as well.

    Solving a Single Variable Equation:

    4.2      Solve  :    x = 0  

     Solution is  x = 0

    Solving a Single Variable Equation:

    4.3      Solve  :    3x-1 = 0  

    Add  1  to both sides of the equation :  

                         3x = 1

    Divide both sides of the equation by 3:

                        x = 1/3 = 0.333

    Two solutions were found :

    x = 1/3 = 0.333

    x = 0
