[ 1/1 Equation]
    Work: Find the solution of equation (51-x)/(39-x) = 4 .
    Question type: Equation
    Solution:Original question:
     (51 x ) ÷ (39 x ) = 4
     Multiply both sides of the equation by:(39 x )
     (51 x ) = 4(39 x )
    Remove a bracket on the left of the equation::
     51 x = 4(39 x )
    Remove a bracket on the right of the equation::
     51 x = 4 × 394 x
    The equation is reduced to :
     51 x = 1564 x

    Transposition :
      - x + 4 x = 15651

    Combine the items on the left of the equation:
     3 x = 15651

    Combine the items on the right of the equation:
     3 x = 105

    The coefficient of the unknown number is reduced to 1 :
      x = 105 ÷ 3
        = 105 ×
1
3
        = 35 × 1

    We obtained :
      x = 35
    This is the solution of the equation.
