[ 1/2 Equation]
    Work: Find the solution of equation 0.3/(x-1)-0.5/(x+2) = 0 .
    Question type: Equation
    Solution:Original question:
     
3
10
÷ ( x 1)
1
2
÷ ( x + 2) = 0
     Multiply both sides of the equation by:( x 1)
     
3
10
1
2
÷ ( x + 2) × ( x 1) = 0
    Remove a bracket on the left of the equation::
     
3
10
1
2
÷ ( x + 2) × x +
1
2
÷ ( x + 2) × 1 = 0
    The equation is reduced to :
     
3
10
1
2
÷ ( x + 2) × x +
1
2
÷ ( x + 2) = 0
     Multiply both sides of the equation by:( x + 2)

3
10
× 2
1
2
x +
1
2
= 0
    The equation is reduced to :
     
3
10
x +
3
5
1
2
x +
1
2
= 0
    The equation is reduced to :
      -
1
5
x +
11
10
= 0

    Transposition :
      -
1
5
x = 0
11
10

    Combine the items on the right of the equation:
      -
1
5
x = -
11
10

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
11
10
=
1
5
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
5
x =
11
10

    The coefficient of the unknown number is reduced to 1 :
      x =
11
10
÷
1
5
        =
11
10
× 5
        =
11
2
× 1

    We obtained :
      x =
11
2
    This is the solution of the equation.

    Convert the result to decimal form :
      x = 5.5
