[ 1/1 Equation]
    Work: Find the solution of equation 2*3*4*5*6*(n-2)-2*3*4*5*(n+7) = 0 .
    Question type: Equation
    Solution:Original question:
     2 × 3 × 4 × 5 × 6( n 2)2 × 3 × 4 × 5( n + 7) = 0
     Left side of the equation = 720( n 2)120( n + 7)
    The equation is transformed into :
     720( n 2)120( n + 7) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = 720 n 720 × 2120( n + 7)
                                             = 720 n 1440120( n + 7)
                                             = 720 n 1440120 n 120 × 7
                                             = 720 n 1440120 n 840
                                             = 600 n 2280
    The equation is transformed into :
     600 n 2280 = 0

    Transposition :
     600 n = 0 + 2280

    Combine the items on the right of the equation:
     600 n = 2280

    The coefficient of the unknown number is reduced to 1 :
      n = 2280 ÷ 600
        = 2280 ×
1
600
        = 19 ×
1
5

    We obtained :
      n =
19
5
    This is the solution of the equation.

    Convert the result to decimal form :
      n = 3.8
