    Work: Find the solution of equation 10000÷x+20000÷(x+66) = 150 .
    Question type: Equation
    Solution:Original question:
     10000 ÷ x + 20000 ÷ ( x + 66) = 150
     Multiply both sides of the equation by: x
     10000 + 20000 ÷ ( x + 66) × x = 150 x
     Multiply both sides of the equation by:( x + 66)
     10000( x + 66) + 20000 x = 150 x ( x + 66)
    Remove a bracket on the left of the equation:
     10000 x + 10000 × 66 + 20000 x = 150 x ( x + 66)
    Remove a bracket on the right of the equation::
     10000 x + 10000 × 66 + 20000 x = 150 x x + 150 x × 66
    The equation is reduced to :
     10000 x + 660000 + 20000 x = 150 x x + 9900 x
    The equation is reduced to :
     30000 x + 660000 = 150 x x + 9900 x

    The solution of the equation:
        x1≈-27.281493 , keep 6 decimal places
        x2≈161.281493 , keep 6 decimal places
    
    There are 2 solution(s).
