[ 1/1 Equation]
    Work: Find the solution of equation (x+225)/(9x+225) = 4x/(25x+2025) .
    Question type: Equation
    Solution:Original question:
     ( x + 225) ÷ (9 x + 225) = 4 x ÷ (25 x + 2025)
     Multiply both sides of the equation by:(9 x + 225) ,  (25 x + 2025)
     ( x + 225)(25 x + 2025) = 4 x (9 x + 225)
    Remove a bracket on the left of the equation::
      x (25 x + 2025) + 225(25 x + 2025) = 4 x (9 x + 225)
    Remove a bracket on the right of the equation::
      x (25 x + 2025) + 225(25 x + 2025) = 4 x × 9 x + 4 x × 225
    The equation is reduced to :
      x (25 x + 2025) + 225(25 x + 2025) = 36 x x + 900 x
    Remove a bracket on the left of the equation:
      x × 25 x + x × 2025 + 225(25 x + 2025) = 36 x x + 900 x
    Remove a bracket on the left of the equation:
      x × 25 x + 2025 x + 225 × 25 x + 225 × 2025 = 36 x x + 900 x
    The equation is reduced to :
      x × 25 x + 2025 x + 5625 x + 455625 = 36 x x + 900 x
    The equation is reduced to :
      x × 25 x + 7650 x + 455625 = 36 x x + 900 x

    the solutions is:
        x1=-
