    Work: Find the solution of equation 7800/(x+12.12)+10000/x+7500/x = 150 .
    Question type: Equation
    Solution:Original question:
     7800 ÷ ( x +
303
25
) + 10000 ÷ x + 7500 ÷ x = 150
     Multiply both sides of the equation by:( x +
303
25
)
     7800 + 10000 ÷ x × ( x +
303
25
) + 7500 ÷ x × ( x +
303
25
) = 150( x +

    Remove a bracket on the left of the equation:：
     7800 + 10000 ÷ x × x + 10000 ÷ x ×
303
25
 + 7500 ÷ x × ( x +
303
25
) = 150( x +
303
25
)
    Remove a bracket on the right of the equation:：
     7800 + 10000 ÷ x × x + 10000 ÷ x ×
303
25
 + 7500 ÷ x × ( x +
303
25
) = 150 x + 150 ×
303
25
    The equation is reduced to :
     7800 + 10000 ÷ x × x + 121200 ÷ x + 7500 ÷ x × ( x +
303
25
) = 150 x + 1818
     Multiply both sides of the equation by: x
     7800 x + 10000 ÷ 1 × 1 x + 121200 + 7500 ÷ 1 × ( x +
303
25
) × 1 = 150 x x + 1818 x
    Remove a bracket on the left of the equation:
     7800 x + 10000 ÷ 1 × 1 x + 121200 + 7500 ÷ 1 × x × 1 + 7500 = 150 x x + 1818 x
    The equation is reduced to :
     7800 x + 10000 x + 121200 + 7500 x + 90900 = 150 x x + 1818 x
    The equation is reduced to :
     25300 x + 212100 = 150 x x + 1818 x

    The solution of the equation:
        x1≈-8.563955 , keep 6 decimal places
        x2≈165.110622 , keep 6 decimal places    
    There are 2 solution(s).
