[ 1/1 Equation]
    Work: Find the solution of equation 7500/x+30000/(x+60) = 150 .
    Question type: Equation
    Solution:Original question:
     7500 ÷ x + 30000 ÷ ( x + 60) = 150
     Multiply both sides of the equation by: x
     7500 + 30000 ÷ ( x + 60) × x = 150 x
     Multiply both sides of the equation by:( x + 60)
     7500( x + 60) + 30000 x = 150 x ( x + 60)
    Remove a bracket on the left of the equation:
     7500 x + 7500 × 60 + 30000 x = 150 x ( x + 60)
    Remove a bracket on the right of the equation::
     7500 x + 7500 × 60 + 30000 x = 150 x x + 150 x × 60
    The equation is reduced to :
     7500 x + 450000 + 30000 x = 150 x x + 9000 x
    The equation is reduced to :
     37500 x + 450000 = 150 x x + 9000 x

    
        x≈-14.658561 , keep 6 decimal places
    
    There are 1 solution(s).
