[ 1/1 Equation]
    Work: Find the solution of equation 30000*110+30000y = 1.3*30000*80+1.3*20000*100 .
    Question type: Equation
    Solution:Original question:
     30000 × 110 + 30000 y =
13
10
 × 30000 × 80 +
13
10
 × 20000 × 100
     Left side of the equation = 3300000 + 30000 y
    The equation is transformed into :
     3300000 + 30000 y =
13
10
 × 30000 × 80 +
13
10
 × 20000 × 100
     Right side of the equation = 3120000 + 2600000
                                               = 5720000
    The equation is transformed into :
     3300000 + 30000 y = 5720000

    Transposition :
     30000 y = 5720000 − 3300000

    Combine the items on the right of the equation:
     30000 y = 2420000

    The coefficient of the unknown number is reduced to 1 :
      y = 2420000 ÷ 30000
        = 2420000 ×
1
30000
        = 242 ×
1
3

    We obtained :
      y =
242
3
    This is the solution of the equation.

    Convert the result to decimal form :
      y = 80.666667
