[ 1/1 Equation]
    Work: Find the solution of equation 7.32+x+（0.61+0.5x/12）*0.487*12 = 21 .
    Question type: Equation
    Solution:Original question:
     
183
25
 + x + (
61
100
 +
1
2
 x ÷ 12) ×
487
1000
 × 12 = 21
     Left side of the equation =
183
25
 + x + (
61
100
 +
1
2
 x ÷ 12) ×
1461

    The equation is transformed into :
     
183
25
 + x + (
61
100
 +
1
2
 x ÷ 12) ×
1461

2487
2000
 x = 21

    Transposition :
     
2487
2000
 x = 21 −
272121
25000

    Combine the items on the right of the equation:
     
2487
2000
 x =
252879
25000

    The coefficient of the unknown number is reduced to 1 :
      x =
252879
25000
 ÷
2487
2000
        =
252879
25000

    We obtained :
      x =
168586
20725
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 8.134427
