[ 1/1 Equation]
    Work: Find the solution of equation (x-250)(8+290-x/5乘4) = 480 .
    Question type: Equation
    Solution:Original question:
     ( x 250)(8 + 290 x ÷ 5 × 4) = 480
    Remove the bracket on the left of the equation:
     Left side of the equation = x (8 + 290 x ÷ 5 × 4)250(8 + 290 x ÷ 5 × 4)
                                             = x × 8 + x × 290 x x ÷ 5 × 4250(8 + 290 x ÷ 5 × 4)
                                             = x × 8 + x × 290 x x ×
