    Work: Find the solution of equation 3000×g×（120%－30%）－3000×（1＋g）×5%×（1－30%）－200 = 0 .
    Question type: Equation
    Solution:Original question:
     3000 g (
120
100
 −
30
100
) − 3000(1 + g ) ×
5
100
(1 −
30
100
) − 200 = 0
     Left side of the equation = 3000 g (
120
100
 −
30
100
) − 150(1 + g )(1 −
30
100
) − 200
    The equation is transformed into :
     3000 g (
120
100
 −
30
100
) − 150(1 + g )(1 −
30
100
) − 200 = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = 3000 g ×
120
100
 − 3000 g ×
30
100
 − 150(1 + g )(1 −
30
100
) − 200
                                             = 3600 g − 900 g − 150(1 + g )(1 −
30
100
) − 200
                                             = 2700 g − 150(1 + g )(1 −
30
100
) − 200
                                             = 2700 g − 150 × 1(1 −
30
100
) − 150 g (1 −
30
100
) − 200
                                             = 2700 g − 150(1 −
30
100
) − 150 g (1 −
30
100
) − 200
                                             = 2700 g − 150 × 1 + 150 ×
30
100
 − 150 g (1 −
30
100
) − 200
                                             = 2700 g − 150 + 45 − 150 g (1 −
30
100
) − 200
                                             = 2700 g − 305 − 150 g (1 −
30
100
)
                                             = 2700 g − 305 − 150 g × 1 + 150 g ×
30
100
                                             = 2700 g − 305 − 150 g + 45 g
                                             = 2595 g − 305
    The equation is transformed into :
     2595 g − 305 = 0

    Transposition :
     2595 g = 0 + 305

    Combine the items on the right of the equation:
     2595 g = 305

    The coefficient of the unknown number is reduced to 1 :
      g = 305 ÷ 2595
        = 305 ×
1
2595
        = 61 ×
1
519

    We obtained :
      g =
61
519
    This is the solution of the equation.

    Convert the result to decimal form :
      g = 0.117534
