[ 1/1 Equation]
    Work: Find the solution of equation 1.2X+1.5-1.5X = 18×2 .
    Question type: Equation
    Solution:Original question:

3
2
X = 18 × 2
     Left side of the equation = -
3
10
X +
3
2
    The equation is transformed into :
      -
3
10
X +
3
2
= 18 × 2
     Right side of the equation = 36
    The equation is transformed into :
      -

    Combine the items on the right of the equation:
      -
3
10
X =
69
2

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
      -
69
2
=
3
10
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 :
     
3
10
X = -
69
2

    The coefficient of the unknown number is reduced to 1 :
      X = -
69

3
        = - 23 × 5

    We obtained :
      X = - 115
    This is the solution of the equation.
