[ 1/1 Equation]
    Work: Find the solution of equation k-(5/13-k)*(5/13-k) = 0 .
    Question type: Equation
    Solution:Original question:
      k (5 ÷ 13 k )(5 ÷ 13 k ) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = k 5 ÷ 13 × (5 ÷ 13 k ) + k (5 ÷ 13 k )
                                             = k
