    Work: Find the solution of equation x/(1+100/100)-x/(1+130/100)+x*2/(1+100/100)-x*2/(1+115/100) = 300 .
    Question type: Equation
    Solution:Original question:
      x ÷ (1 + 100 ÷ 100) − x ÷ (1 + 130 ÷ 100) + x × 2 ÷ (1 + 100 ÷ 100) − x × 2 ÷ (1 + 115 ÷ 100) = 300
     Multiply both sides of the equation by:(1 + 100 ÷ 100)
      x − x ÷ (1 + 130 ÷ 100) × (1 + 100 ÷ 100) + x × 2 ÷ (1 + 100 ÷ 100) × (1 + 100 ÷ 100) − x × 2 ÷ (1 + 115 ÷ 100) × (1 + 100 ÷ 100) = 300(1 + 100 ÷ 100)
    Remove a bracket on the left of the equation:：
      x − x ÷ (1 + 130 ÷ 100) × 1 − x ÷ (1 + 130 ÷ 100) × 100 ÷ 100 + x × 2 ÷ (1 + 100 ÷ 100) × (1 + 100 ÷ 100) = 300(1 + 100 ÷ 100)
    Remove a bracket on the right of the equation:：
      x − x ÷ (1 + 130 ÷ 100) × 1 − x ÷ (1 + 130 ÷ 100) × 100 ÷ 100 + x × 2 ÷ (1 + 100 ÷ 100) × (1 + 100 ÷ 100) = 300 × 1 + 300 × 100 ÷ 100
    The equation is reduced to :
      x − x ÷ (1 + 130 ÷ 100) × 1 − x ÷ (1 + 130 ÷ 100) × 1 + x × 2 ÷ (1 + 100 ÷ 100) × (1 + 100 ÷ 100) − x = 300 + 300
    The equation is reduced to :
      x − x ÷ (1 + 130 ÷ 100) × 1 − x ÷ (1 + 130 ÷ 100) × 1 + x × 2 ÷ (1 + 100 ÷ 100) × (1 + 100 ÷ 100) − x = 600
     Multiply both sides of the equation by:(1 + 130 ÷ 100)
      x (1 + 130 ÷ 100) − x × 1 − x ÷ (1 + 130 ÷ 100) × 1(1 + 130 ÷ 100) + x × 2 ÷ (1 + 100 ÷ 100) × (1 + 100 ÷ 100) = 600(1 + 130 ÷ 100)
    Remove a bracket on the left of the equation:
      x × 1 + x × 130 ÷ 100 − x × 1 − x ÷ (1 + 130 ÷ 100) × 1(1 + 130 ÷ 100) + x = 600(1 + 130 ÷ 100)
    Remove a bracket on the right of the equation:：
      x × 1 + x × 130 ÷ 100 − x × 1 − x ÷ (1 + 130 ÷ 100) × 1(1 + 130 ÷ 100) + x = 600 × 1 + 600 × 130 ÷ 100
    The equation is reduced to :
