[ 1/1 Equation]
    Work: Find the solution of equation (X-6970)/(760-6970) = (500-480)/(540-480) .
    Question type: Equation
    Solution:Original question:
     ( X − 6970) ÷ (760 − 6970) = (500 − 480) ÷ (540 − 480)
     Multiply both sides of the equation by:(760 − 6970) ,  (540 − 480)
     ( X − 6970)(540 − 480) = (500 − 480)(760 − 6970)
    Remove a bracket on the left of the equation::
      X (540 − 480) − 6970(540 − 480) = (500 − 480)(760 − 6970)
    Remove a bracket on the right of the equation::
      X (540 − 480) − 6970(540 − 480) = 500(760 − 6970) − 480(760 − 6970)
    Remove a bracket on the left of the equation:
      X × 540 − X × 480 − 6970(540 − 480) = 500(760 − 6970) − 480(760 − 6970)
    Remove a bracket on the right of the equation::
      X × 540 − X × 480 − 6970(540 − 480) = 500 × 760 − 500 × 6970 − 480(760 − 6970)
    The equation is reduced to :
      X × 540 − X × 480 − 6970(540 − 480) = 380000 − 3485000 − 480(760 − 6970)
    The equation is reduced to :
     60 X − 6970(540 − 480) = - 3105000 − 480(760 − 6970)
    Remove a bracket on the left of the equation:
     60 X − 6970 × 540 + 6970 × 480 = - 3105000 − 480(760 − 6970)
    Remove a bracket on the right of the equation::
     60 X − 6970 × 540 + 6970 × 480 = - 3105000 − 480 × 760 + 480 × 6970
    The equation is reduced to :
     60 X − 3763800 + 3345600 = - 3105000 − 364800 + 3345600
    The equation is reduced to :
     60 X − 418200 = - 124200

    Transposition :
     60 X = - 124200 + 418200

    Combine the items on the right of the equation:
     60 X = 294000

    The coefficient of the unknown number is reduced to 1 :
      X = 294000 ÷ 60
        = 294000 ×
1
60
        = 4900 × 1

    We obtained :
      X = 4900
    This is the solution of the equation.
