[ 1/1 Equation]
    Work: Find the solution of equation 21x(99-11×31+28×48) = 0 .
    Question type: Equation
    Solution:Original question:
     21 x (9911 × 31 + 28 × 48) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation = 21 x × 9921 x × 11 × 31 + 21 x × 28 × 48
                                             = 2079 x 7161 x + 28224 x
                                             = 23142 x
    The equation is transformed into :
     23142 x = 0

    The coefficient of the unknown number is reduced to 1 :
      x = 0 ÷ 23142
        = 0 ×
1
23142

    We obtained :
      x = 0
    This is the solution of the equation.
