[ 1/1 Equation]
    Work: Find the solution of equation 10x(x-3) = [10x+(x-3)]2/7 .
    Question type: Equation
    Solution:Original question:
     10 x ( x 3) = (10 x + ( x 3)) × 2 ÷ 7
    Remove the bracket on the left of the equation:
     Left side of the equation = 10 x x 10 x × 3
                                             = 10 x x 30 x
    The equation is transformed into :
     10 x x 30 x = (10 x + ( x 3)) × 2 ÷ 7
     Right side of the equation = (10 x + ( x 3)) ×
