[ 1/1 Equation]
    Work: Find the solution of equation [50000*（1+7.5%)+y]*12% = 50000*7.5%+3000 .
    Question type: Equation
    Solution:Original question:
     (50000(1 +
15
200
) + y ) ×
12
100
 = 50000 ×
15
200
 + 3000
    Remove the bracket on the left of the equation:
     Left side of the equation = 50000(1 +
15
200
) ×
12
100
 + y ×
12
100
                                             = 6000(1 +
15
200
) + y ×
12
100
                                             = 6000 × 1 + 6000 ×
15
200
 +
12
100
 y
                                             = 6000 + 450 +
12
100
 y
                                             = 6450 +
12
100
 y
    The equation is transformed into :
     6450 +
12
100
 y = 50000 ×
15
200
 + 3000
     Right side of the equation = 3750 + 3000
                                               = 6750
    The equation is transformed into :
     6450 +
12
100
 y = 6750

    Transposition :
     
12
100
 y = 6750 − 6450

    Combine the items on the right of the equation:
     
12
100
 y = 300

    The coefficient of the unknown number is reduced to 1 :
      y = 300 ÷
12
100
        = 300 ×
100
12
        = 25 × 100

    We obtained :
      y = 2500
    This is the solution of the equation.
