[ 1/1 Equation]
    Work: Find the solution of equation 7500/(x+11)+10000/x*2 = 429 .
    Question type: Equation
    Solution:Original question:
     7500 ÷ ( x + 11) + 10000 ÷ x × 2 = 429
     Multiply both sides of the equation by:( x + 11)
     7500 + 10000 ÷ x × 2( x + 11) = 429( x + 11)
    Remove a bracket on the left of the equation::
     7500 + 10000 ÷ x × 2 x + 10000 ÷ x × 2 × 11 = 429( x + 11)
    Remove a bracket on the right of the equation::
     7500 + 10000 ÷ x × 2 x + 10000 ÷ x × 2 × 11 = 429 x + 429 × 11
    The equation is reduced to :
     7500 + 20000 ÷ x × x + 220000 ÷ x = 429 x + 4719
     Multiply both sides of the equation by: x
     7500 x + 20000 ÷ 1 × 1 x + 220000 = 429 x x + 4719 x

    The solution of the equation:
        x1≈-8.345582 , keep 6 decimal places
        x2≈61.448146 , keep 6 decimal places
    
    There are 2 solution(s).
