    Work: Find the solution of equation 1200/(x-50) = 800-(x-60)×20 .
    Question type: Equation
    Solution:Original question:
     1200 ÷ ( x 50) = 800( x 60) × 20
     Multiply both sides of the equation by:( x 50)
     1200 = 800( x 50)( x 60) × 20( x 50)
    Remove a bracket on the right of the equation::
     1200 = 800 x 800 × 50( x 60) × 20( x 50)
    The equation is reduced to :
     1200 = 800 x 40000( x 60) × 20( x 50)
    Remove a bracket on the right of the equation::
     1200 = 800 x 40000 x × 20( x 50) + 60 × 20( x 50)
    The equation is reduced to :
     1200 = 800 x 40000 x × 20( x 50) + 1200( x 50)
    Remove a bracket on the right of the equation::
     1200 = 800 x 40000 x × 20 x + x × 20 × 50 + 1200( x 50)
    The equation is reduced to :
     1200 = 800 x 40000 x × 20 x + x × 1000 + 1200( x 50)
    The equation is reduced to :
     1200 = 1800 x 40000 x × 20 x + 1200( x 50)
    Remove a bracket on the right of the equation::
     1200 = 1800 x 40000 x × 20 x + 1200 x 1200 × 50
    The equation is reduced to :
     1200 = 1800 x 40000 x × 20 x + 1200 x 60000
    The equation is reduced to :
     1200 = 3000 x 100000 x × 20 x

    The solution of the equation:
        x1≈51.230271 , keep 6 decimal places
        x2≈98.769729 , keep 6 decimal places
    
    There are 2 solution(s).
