[ 1/1 Equation]
    Work: Find the solution of equation (t+2)(-(t/3)+6) = 6t .
    Question type: Equation
    Solution:Original question:
     ( t + 2)( - ( t ÷ 3) + 6) = 6 t
    Remove the bracket on the left of the equation:
     Left side of the equation = t ( - ( t ÷ 3) + 6) + 2( - ( t ÷ 3) + 6)
                                             = - t ( t ÷ 3) + t × 6 + 2( - ( t ÷ 3) + 6)
                                             = - t t ÷ 3 + 6 t + 2( - ( t ÷ 3) + 6)
                                             = - t t ×
