[ 1/1 Equation]
    Work: Find the solution of equation ((2500-x)/4+300)(1+2(2500-x)/1750) = x .
    Question type: Equation
    Solution:Original question:
     ((2500 x ) ÷ 4 + 300)(1 + 2(2500 x ) ÷ 1750) = x
    Remove the bracket on the left of the equation:
     Left side of the equation = (2500 x ) ÷ 4 × (1 + 2(2500 x ) ÷ 1750) + 300(1 + 2(2500 x ) ÷ 1750)
                                             = 2500 ×
