x = 324

    Combine the items on the left of the equation:
     4 x = 324

    Combine the items on the right of the equation:
     4 x = 28

    The coefficient of the unknown number is reduced to 1 :
      x = 28 ÷ 4
        = 28 ×

4
        = 7 × 1

    We obtained :
      x = 7
    This is the solution of the equation.
