    Work: Find the solution of equation X-[(25215.03+X-20000)*0.03-309.03] = 7491 .
    Question type: Equation
    Solution:Original question:
      X − ((
2521503
100
 + X − 20000) ×
3
100
 −
30903
100
) = 7491
    Remove the bracket on the left of the equation:
     Left side of the equation = X − (
2521503
100
 + X − 20000) ×

    The equation is transformed into :
     
97
100
 X +
1525791
10000
 = 7491

    Transposition :
     
97
100
 X = 7491 −
1525791
10000

    Combine the items on the right of the equation:
     
97
100
 X =
73384209
10000

    The coefficient of the unknown number is reduced to 1 :
      X =
73384209
10000
 ÷
97
100
        =

    We obtained :
      X =
73384209
9700
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 7565.382371
