    Work: Find the solution of equation (1/(n-3)+1/(n+6))*3+1/(n+6)*(n-3) = 0 .
    Question type: Equation
    Solution:Original question:
     (1 ÷ ( n 3) + 1 ÷ ( n + 6)) × 3 + 1 ÷ ( n + 6) × ( n 3) = 0
     Multiply both sides of the equation by:( n + 6)
     (1 ÷ ( n 3) + 1 ÷ ( n + 6)) × 3( n + 6) + 1( n 3) = 0
    Remove a bracket on the left of the equation::
     1 ÷ ( n 3) × 3( n + 6) + 1 ÷ ( n + 6) × 3( n + 6) + 1( n 3) = 0
    The equation is reduced to :
     3 ÷ ( n 3) × ( n + 6) + 3 ÷ ( n + 6) × ( n + 6) + 1( n 3) = 0
     Multiply both sides of the equation by:( n 3)
     3( n + 6) + 3 ÷ ( n + 6) × ( n + 6)( n 3) + 1( n 3)( n 3) = 0
    Remove a bracket on the left of the equation:
     3 n + 3 × 6 + 3 ÷ ( n + 6) × ( n + 6)( n 3) + 1( n 3)( n 3) = 0
    The equation is reduced to :
     3 n + 18 + 3 ÷ ( n + 6) × ( n + 6)( n 3) + 1( n 3)( n 3) = 0
     Multiply both sides of the equation by:( n + 6)
     3 n ( n + 6) + 18( n + 6) + 3( n + 6)( n 3) + 1( n 3)( n 3)( n + 6) = 0
    Remove a bracket on the left of the equation:
     3 n n + 3 n × 6 + 18( n + 6) + 3( n + 6)( n 3) + 1 = 0
    The equation is reduced to :
     3 n n + 18 n + 18( n + 6) + 3( n + 6)( n 3) + 1( n 3) = 0
    Remove a bracket on the left of the equation:
     3 n n + 18 n + 18 n + 18 × 6 + 3( n + 6)( n 3) = 0
    The equation is reduced to :
     3 n n + 18 n + 18 n + 108 + 3( n + 6)( n 3) + 1 = 0
    The equation is reduced to :
     3 n n + 36 n + 108 + 3( n + 6)( n 3) + 1( n 3)( n 3) = 0
    Remove a bracket on the left of the equation:
     3 n n + 36 n + 108 + 3 n ( n 3) + 3 × 6( n 3) = 0
    The equation is reduced to :
     3 n n + 36 n + 108 + 3 n ( n 3) + 18( n 3) + 1 = 0
    Remove a bracket on the left of the equation:
     3 n n + 36 n + 108 + 3 n n 3 n × 3 = 0
    The equation is reduced to :
     3 n n + 36 n + 108 + 3 n n 9 n + 18 = 0
    The equation is reduced to :
     3 n n + 27 n + 108 + 3 n n + 18( n 3) + 1 = 0
    Remove a bracket on the left of the equation:
     3 n n + 27 n + 108 + 3 n n + 18 n 18 = 0
    The equation is reduced to :
     3 n n + 27 n + 108 + 3 n n + 18 n 54 = 0
    The equation is reduced to :
     3 n n + 45 n + 54 + 3 n n + 1( n 3)( n 3) = 0
    Remove a bracket on the left of the equation:
     3 n n + 45 n + 54 + 3 n n + 1 n ( n 3) = 0
    The equation is reduced to :
     3 n n + 45 n + 54 + 3 n n + 1 n ( n 3) = 0
    
    There are 0 solution(s).
