[ 1/1 Equation]
    Work: Find the solution of equation 10+(2400-10x)/(x+30) = 2400/x-2 .
    Question type: Equation
    Solution:Original question:
     10 + (240010 x ) ÷ ( x + 30) = 2400 ÷ x 2
     Multiply both sides of the equation by:( x + 30) ,   x
     10( x + 30) x + (240010 x ) x = 2400( x + 30)2( x + 30) x
    Remove a bracket on the left of the equation::
     10 x x + 10 × 30 x + (240010 x ) x = 2400( x + 30)2( x + 30) x
    Remove a bracket on the right of the equation::
     10 x x + 10 × 30 x + (240010 x ) x = 2400 x + 2400 × 302( x + 30) x
    The equation is reduced to :
     10 x x + 300 x + (240010 x ) x = 2400 x + 720002( x + 30) x
    Remove a bracket on the left of the equation:
     10 x x + 300 x + 2400 x 10 x x = 2400 x + 720002( x + 30) x
    Remove a bracket on the right of the equation::
     10 x x + 300 x + 2400 x 10 x x = 2400 x + 720002 x x 2 × 30 x
    The equation is reduced to :
     10 x x + 300 x + 2400 x 10 x x = 2400 x + 720002 x x 60 x
    The equation is reduced to :
     10 x x + 2700 x 10 x x = 2340 x + 720002 x x

    the solutions is:
        x1=120
    
    There are 1 solution(s).
