[ 1/1 Equation]
    Work: Find the solution of equation 10(2x+3)+x = 10+x(2x+3)+5 .
    Question type: Equation
    Solution:Original question:
     10(2 x + 3) + x = 10 + x (2 x + 3) + 5
    Remove the bracket on the left of the equation:
     Left side of the equation = 10 × 2 x + 10 × 3 + x
                                             = 20 x + 30 + x
                                             = 21 x + 30
    The equation is transformed into :
     21 x + 30 = 10 + x (2 x + 3) + 5
     Right side of the equation = 15 + x (2 x + 3)
    The equation is transformed into :
     21 x + 30 = 15 + x (2 x + 3)
    Remove the bracket on the right of the equation:
     Right side of the equation = 15 + x × 2 x + x × 3
    The equation is transformed into :
     21 x + 30 = 15 + x × 2 x + 3 x

    The solution of the equation:
        x1≈-0.767827 , keep 6 decimal places
        x2≈9.767827 , keep 6 decimal places
    
    There are 2 solution(s).
