[ 1/1 Equation]
    Work: Find the solution of equation (a-480)/(2a-240) = 480/(a+240) .
    Question type: Equation
    Solution:Original question:
     ( a 480) ÷ (2 a 240) = 480 ÷ ( a + 240)
     Multiply both sides of the equation by:(2 a 240) ,  ( a + 240)
     ( a 480)( a + 240) = 480(2 a 240)
    Remove a bracket on the left of the equation::
      a ( a + 240)480( a + 240) = 480(2 a 240)
    Remove a bracket on the right of the equation::
      a ( a + 240)480( a + 240) = 480 × 2 a 480 × 240
    The equation is reduced to :
      a ( a + 240)480( a + 240) = 960 a 115200
    Remove a bracket on the left of the equation:
      a a + a × 240480( a + 240) = 960 a 115200
    Remove a bracket on the left of the equation:
      a a + 240 a 480 a 480 × 240 = 960 a 115200
    The equation is reduced to :
      a a + 240 a 480 a 115200 = 960 a 115200
    The equation is reduced to :
      a a 240 a 115200 = 960 a 115200

    
        a1=0
    
    There are 1 solution(s).
