[ 1/1 Equation]
    Work: Find the solution of equation 2x+(3x-20) = 5 .
    Question type: Equation
    Solution:Original question:
     2 x + (3 x 20) = 5
    Remove the bracket on the left of the equation:
     Left side of the equation = 2 x + 3 x 20
                                             = 5 x 20
    The equation is transformed into :
     5 x 20 = 5

    Transposition :
     5 x = 5 + 20

    Combine the items on the right of the equation:
     5 x = 25

    The coefficient of the unknown number is reduced to 1 :
      x = 25 ÷ 5
        = 25 ×
1
5
        = 5 × 1

    We obtained :
      x = 5
    This is the solution of the equation.
