[ 1/1 Equation]
    Work: Find the solution of equation 7.32+X+(（X/2/12）+0.61)*48.7%*12 = 21 .
    Question type: Equation
    Solution:Original question:
     
183
25
 + X + (( X ÷ 2 ÷ 12) +
61
100
) ×
487
1000
 × 12 = 21
     Left side of the equation =
183
25
 + X + (( X ÷ 2 ÷ 12) +
61
100
) ×
1461
250
    The equation is transformed into :
     
183
25
 + X + (( X ÷ 2 ÷ 12) +
61
100
) ×
1461
250
 = 21
    Remove the bracket on the left of the equation:
     Left side of the equation =
183
25
 + X + ( X ÷ 2 ÷ 12) ×
1461
250
 +
61
100
 ×
1461
250
                                             =

                                             =
272121
25000
 + X + ( X ÷ 2 ÷ 12) ×
1461
250
                                             =
272121
25000
 + X + X ÷ 2 ÷ 12 ×
1461

 X
    The equation is transformed into :
     
272121
25000
 +
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
 ×
2000
2487
        =
84293
25
 ×
2
829

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

    Convert the result to decimal form :
      X = 8.134427
