[ 1/1 Equation]
    Work: Find the solution of equation 3X+2(2X-1) = 22 .
    Question type: Equation
    Solution:Original question:
     3 X + 2(2 X 1) = 22
    Remove the bracket on the left of the equation:
     Left side of the equation = 3 X + 2 × 2 X 2 × 1
                                             = 3 X + 4 X 2
                                             = 7 X 2
    The equation is transformed into :
     7 X 2 = 22

    Transposition :
     7 X = 22 + 2

    Combine the items on the right of the equation:
     7 X = 24

    The coefficient of the unknown number is reduced to 1 :
      X = 24 ÷ 7
        = 24 ×
1
7

    We obtained :
      X =
24
7
    This is the solution of the equation.

    Convert the result to decimal form :
      X = 3.428571
