    Work: Find the solution of equation 500/(x-25)+30(x-25)/x = 30 .
    Question type: Equation
    Solution:Original question:
     500 ÷ ( x 25) + 30( x 25) ÷ x = 30
     Multiply both sides of the equation by:( x 25)
     500 + 30( x 25) ÷ x × ( x 25) = 30( x 25)
    Remove a bracket on the left of the equation::
     500 + 30 x ÷ x × ( x 25)30 × 25 ÷ x × ( x 25) = 30( x 25)
    Remove a bracket on the right of the equation::
     500 + 30 x ÷ x × ( x 25)30 × 25 ÷ x × ( x 25) = 30 x 30 × 25
    The equation is reduced to :
     500 + 30 x ÷ x × ( x 25)750 ÷ x × ( x 25) = 30 x 750
     Multiply both sides of the equation by: x
     500 x + 30 × 1 ÷ 1 × ( x 25) x 750( x 25) = 30 x x 750 x
    Remove a bracket on the left of the equation:
     500 x + 30 × 1 ÷ 1 × x x 30 × 1 ÷ 1 × 25 x = 30 x x 750 x
    The equation is reduced to :
     500 x + 30 x x 750 x 750( x 25) = 30 x x 750 x
    The equation is reduced to :
      - 250 x + 30 x x 750( x 25) = 30 x x 750 x
    Remove a bracket on the left of the equation:
      - 250 x + 30 x x 750 x + 750 × 25 = 30 x x 750 x
    The equation is reduced to :
      - 250 x + 30 x x 750 x + 18750 = 30 x x 750 x
    The equation is reduced to :
      - 1000 x + 30 x x + 18750 = 30 x x 750 x

    
        x1=75
    
    There are 1 solution(s).
