    Work: Find the solution of equation (X-180)/(1000+500) = (X-180-4000×8%)/1000 .
    Question type: Equation
    Solution:Original question:
     ( X 180) ÷ (1000 + 500) = ( X 1804000 ×
8
100
) ÷ 1000
     Multiply both sides of the equation by:(1000 + 500)
     ( X 180) = ( X 1804000 ×
8
100
) ÷ 1000 × (1000 + 500)
    Remove a bracket on the left of the equation::
      X 180 = ( X 1804000 ×
8
100
) ÷ 1000 × (1000 + 500)
    Remove a bracket on the right of the equation::
      X 180 = X ÷ 1000 × (1000 + 500)180 ÷ 1000 × (1000 + 500)4000 ×

    The equation is reduced to :
      X 180 =

X 750

    Transposition :
      X

2
X = - 750 + 180

    Combine the items on the left of the equation:
      -
1
2
X = - 750 + 180

    Combine the items on the right of the equation:
      -
1
2
X = - 570

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     570 =
1
2
X

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
1
2
X = 570

    The coefficient of the unknown number is reduced to 1 :
      X = 570 ÷
1
2
        = 570 × 2

    We obtained :
      X = 1140
    This is the solution of the equation.
