[ 1/1 Equation]
    Work: Find the solution of equation x = -100+0.2（x-250+62.5）+250 .
    Question type: Equation
    Solution:Original question:
      x = - 100 +
1
5
( x − 250 +
125
2
) + 250
     Right side of the equation = 150 +

5
( x − 250 +
125
2
)
    The equation is transformed into :
      x = 150 +
1
5
( x − 250 +
125
2
)
    Remove the bracket on the right of the equation:
     Right side of the equation = 150 +

    We obtained :
      x =
1125
8
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 140.625
