[ 1/1 Equation]
    Work: Find the solution of equation (m-1)/(m+3)-(2/m-1) = 1 .
    Question type: Equation
    Solution:Original question:
     ( m 1) ÷ ( m + 3)(2 ÷ m 1) = 1
     Multiply both sides of the equation by:( m + 3)
     ( m 1)(2 ÷ m 1)( m + 3) = 1( m + 3)
    Remove a bracket on the left of the equation::
      m 1(2 ÷ m 1)( m + 3) = 1( m + 3)
    Remove a bracket on the right of the equation::
      m 1(2 ÷ m 1)( m + 3) = 1 m + 1 × 3
    The equation is reduced to :
      m 1(2 ÷ m 1)( m + 3) = 1 m + 3
    Remove a bracket on the left of the equation:
      m 12 ÷ m × ( m + 3) + 1( m + 3) = 1 m + 3
     Multiply both sides of the equation by: m
      m m 1 m 2( m + 3) + 1( m + 3) m = 1 m m + 3 m
    Remove a bracket on the left of the equation:
      m m 1 m 2 m 2 × 3 + 1( m + 3) m = 1 m m + 3 m
    The equation is reduced to :
      m m 1 m 2 m 6 + 1( m + 3) m = 1 m m + 3 m
    The equation is reduced to :
      m m 3 m 6 + 1( m + 3) m = 1 m m + 3 m
    Remove a bracket on the left of the equation:
      m m 3 m 6 + 1 m m + 1 × 3 m = 1 m m + 3 m
    The equation is reduced to :
      m m 3 m 6 + 1 m m + 3 m = 1 m m + 3 m
    The equation is reduced to :
      m m 0 m 6 + 1 m m = 1 m m + 3 m

    The solution of the equation:
        m1≈-1.372281 , keep 6 decimal places
        m2≈4.372281 , keep 6 decimal places
    
    There are 2 solution(s).
