[ 1/1 Equation]
    Work: Find the solution of equation Q*(25440-12*Q) = (15*Q-4200)*(2300-Q) .
    Question type: Equation
    Solution:Original question:
      Q (2544012 Q ) = (15 Q 4200)(2300 Q )
    Remove the bracket on the left of the equation:
     Left side of the equation = Q × 25440 Q × 12 Q
    The equation is transformed into :
     25440 Q Q × 12 Q = (15 Q 4200)(2300 Q )
    Remove the bracket on the right of the equation:
     Right side of the equation = 15 Q (2300 Q )4200(2300 Q )
                                               = 15 Q × 230015 Q Q 4200(2300 Q )
                                               = 34500 Q 15 Q Q 4200(2300 Q )
                                               = 34500 Q 15 Q Q 4200 × 2300 + 4200 Q
                                               = 34500 Q 15 Q Q 9660000 + 4200 Q
                                               = 38700 Q 15 Q Q 9660000
    The equation is transformed into :
     25440 Q Q × 12 Q = 38700 Q 15 Q Q 9660000

    
        Q=920
    
    There are 1 solution(s).
