[ 1/1 Equation]
    Work: Find the solution of equation 7x+2(3x-3) = 20 .
    Question type: Equation
    Solution:Original question:
     7 x + 2(3 x 3) = 20
    Remove the bracket on the left of the equation:
     Left side of the equation = 7 x + 2 × 3 x 2 × 3
                                             = 7 x + 6 x 6
                                             = 13 x 6
    The equation is transformed into :
     13 x 6 = 20

    Transposition :
     13 x = 20 + 6

    Combine the items on the right of the equation:
     13 x = 26

    The coefficient of the unknown number is reduced to 1 :
      x = 26 ÷ 13
        = 26 ×
1
13
        = 2 × 1

    We obtained :
      x = 2
    This is the solution of the equation.
