[ 1/1 Equation]
    Work: Find the solution of equation m+1/(1-m)+(1-1/m)-1+1/2+2 = 71/12 .
    Question type: Equation
    Solution:Original question:
      m + 1 ÷ (1 m ) + (11 ÷ m )1 + 1 ÷ 2 + 2 = 71 ÷ 12
     Multiply both sides of the equation by:(1 m )
      m (1 m ) + 1 + (11 ÷ m )(1 m )1(1 m ) + 1 ÷ 2 × (1 m ) + 2(1 m ) = 71 ÷ 12 × (1 m )
    Remove a bracket on the left of the equation::
      m × 1 m m + 1 + (11 ÷ m )(1 m )1(1 m ) + 1 ÷ 2 × (1 m ) = 71 ÷ 12 × (1 m )
    Remove a bracket on the right of the equation::
      m × 1 m m + 1 + (11 ÷ m )(1 m )1(1 m ) + 1 ÷ 2 × (1 m ) = 71 ÷ 12 × 171 ÷ 12 × m
    The equation is reduced to :
      m × 1 m m + 1 + (11 ÷ m )(1 m )1(1 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=-

        m3=4
    
    There are 3 solution(s).
