    Work: Find the solution of equation 7800/x+10000/(x+22)+10000/x = 150 .
    Question type: Equation
    Solution:Original question:
     7800 ÷ x + 10000 ÷ ( x + 22) + 10000 ÷ x = 150
     Multiply both sides of the equation by: x
     7800 + 10000 ÷ ( x + 22) × x + 10000 ÷ 1 × 1 = 150 x
     Multiply both sides of the equation by:( x + 22)
     7800( x + 22) + 10000 x + 10000 ÷ 1 × 1( x + 22) = 150 x ( x + 22)
    Remove a bracket on the left of the equation:
     7800 x + 7800 × 22 + 10000 x + 10000 ÷ 1 × 1( x + 22) = 150 x ( x + 22)
    Remove a bracket on the right of the equation::
     7800 x + 7800 × 22 + 10000 x + 10000 ÷ 1 × 1( x + 22) = 150 x x + 150 x × 22
    The equation is reduced to :
     7800 x + 171600 + 10000 x + 10000( x + 22) = 150 x x + 3300 x
    The equation is reduced to :
     17800 x + 171600 + 10000( x + 22) = 150 x x + 3300 x
    Remove a bracket on the left of the equation:
     17800 x + 171600 + 10000 x + 10000 × 22 = 150 x x + 3300 x
    The equation is reduced to :
     17800 x + 171600 + 10000 x + 220000 = 150 x x + 3300 x
    The equation is reduced to :
     27800 x + 391600 = 150 x x + 3300 x

    After the equation is converted into a general formula, it is converted into:
    ( 3x + 44 )( x - 178 )=0
    From
        3x + 44 = 0
        x - 178 = 0

    it is concluded that::
        x1=-
44
3
        x2=178
    
    There are 2 solution(s).
