[ 1/1 Equation]
    Work: Find the solution of equation (72.5+20.5)*x+72.5*12 = 1800 .
    Question type: Equation
    Solution:Original question:
     (
145
2
+
41
2
) x +
145
2
× 12 = 1800
     Left side of the equation = (
145
2
+
41
2
) x + 870
    The equation is transformed into :
     (
145
2
+
41
2
) x + 870 = 1800
    Remove the bracket on the left of the equation:
     Left side of the equation =
145
2
x +
41
2
x + 870
                                             = 93 x + 870
    The equation is transformed into :
     93 x + 870 = 1800

    Transposition :
     93 x = 1800870

    Combine the items on the right of the equation:
     93 x = 930

    The coefficient of the unknown number is reduced to 1 :
      x = 930 ÷ 93
        = 930 ×
1
93
        = 10 × 1

    We obtained :
      x = 10
    This is the solution of the equation.
