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

2
a − 1 a − 1 × 240 = 2 a − 240
    The equation is reduced to :
      a ×
1
480
a +
1
2
a − 1 a − 240 = 2 a − 240
    The equation is reduced to :
      a ×

a − 240 = 2 a − 240

    
        a=0
    
    There are 1 solution(s).
