[ 1/1 Equation]
    Work: Find the solution of equation 12x[1−(1+4%)−(75.21−60)]/0.04x（1+4%） = 139 .
    Question type: Equation
    Solution:Original question:
     12 x (1 − (1 +

100
) − (
7521
100
 − 60)) ÷
1
25
 × x (1 +
4

) = 139
     Left side of the equation = 300 x (1 − (1 +
4
100
) − (
7521
100
 − 60)) x (1 +

)
    The equation is transformed into :
     300 x (1 − (1 +
4
100
) − (
7521
100
 − 60)) x (1 +

) = 139
    Remove the bracket on the left of the equation:
     Left side of the equation = 300 x × 1 x (1 +

) − 300
                                             = 300 x x + 12 x x − 300 x x (1 +

) − 12 x
                                             = 300 x x + 12 x x − 300 x x × 1 − 300 x
                                             = 300 x x + 12 x x − 300 x x − 12 x x
                                             = 300 x x + 12 x x − 300 x x − 12 x x
                                             = 300 x x + 12 x x − 300 x x − 12 x x
                                             = 300 x x + 12 x x − 300 x x − 12 x x
                                             = 300 x x + 12 x x − 300 x x − 12 x x
                                             = 300 x x + 12 x x − 300 x x − 12 x x
                                             = 300 x x + 12 x x − 300 x x − 12 x x
                                             = 300 x x + 12 x x − 300 x x − 12 x x
                                             = 300 x x + 12 x x − 300 x x − 12 x x
    The equation is transformed into :
     300 x x + 12 x x − 300 x x − 12 x x = 139
    This equation has no real solution!
