[ 1/1 Equation]
    Work: Find the solution of equation 42×120×（0.075+x÷100×0.0225）+50 = 572 .
    Question type: Equation
    Solution:Original question:
     42 × 120(
3
40
 + x ÷ 100 ×
9
400
) + 50 = 572
     Left side of the equation = 5040(
3
40
 + x ÷ 100 ×
9
400
) + 50
    The equation is transformed into :
     5040(
3
40
 + x ÷ 100 ×
9
400
) + 50 = 572
    Remove the bracket on the left of the equation:
     Left side of the equation = 5040 ×
3
40
 + 5040 x ÷ 100 ×
9
400
 + 50
                                             = 378 +
567
500
 x + 50
                                             = 428 +
567
500
 x
    The equation is transformed into :
     428 +
567
500
 x = 572

    Transposition :
     
567
500
 x = 572 − 428

    Combine the items on the right of the equation:
     
567
500
 x = 144

    The coefficient of the unknown number is reduced to 1 :
      x = 144 ÷
567
500
        = 144 ×
500
567
        = 16 ×
500
63

    We obtained :
      x =
8000
63
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 126.984127
