[ 1/1 Equation]
    Work: Find the solution of equation m+1/(1-m)+(m-1)/m = 53/12 .
    Question type: Equation
    Solution:Original question:
      m + 1 ÷ (1 m ) + ( m 1) ÷ m = 53 ÷ 12
     Multiply both sides of the equation by:(1 m )
      m (1 m ) + 1 + ( m 1) ÷ m × (1 m ) = 53 ÷ 12 × (1 m )
    Remove a bracket on the left of the equation::
      m × 1 m m + 1 + ( m 1) ÷ m × (1 m ) = 53 ÷ 12 × (1 m )
    Remove a bracket on the right of the equation::
      m × 1 m m + 1 + ( m 1) ÷ m × (1 m ) = 53 ÷ 12 × 153 ÷ 12 × m
    The equation is reduced to :
      m × 1 m m + 1 + ( m 1) ÷ m × (1 m ) =
53
12
53
12
m
     Multiply both sides of the equation by: m
     1 m m m m m + 1 m + ( m 1)(1 m ) =

    Remove a bracket on the left of the equation:
     1 m m m m m + 1 m + m (1 m )1(1 m ) =

    The equation is reduced to :
     1 m m m m m + 3 m m m 1 =

m m

    After the equation is converted into a general formula, it is converted into:
    ( 3m + 1 )( 4m - 3 )( m - 4 )=0
    From
        3m + 1 = 0
        4m - 3 = 0
        m - 4 = 0

    it is concluded that::
        m1=-
1
3
        m2=
3
4
        m3=4
    
    There are 3 solution(s).
