[ 1/1 Equation]
    Work: Find the solution of equation (1/a-4)+(2/1-2a) = (1/a-2)+(4/1-4a) .
    Question type: Equation
    Solution:Original question:
     (1 ÷ a − 4) + (2 ÷ 1 − 2 a ) = (1 ÷ a − 2) + (4 ÷ 1 − 4 a )
    Remove a bracket on the left of the equation::
     1 ÷ a − 4 + (2 ÷ 1 − 2 a ) = (1 ÷ a − 2) + (4 ÷ 1 − 4 a )
    Remove a bracket on the right of the equation::
     1 ÷ a − 4 + (2 ÷ 1 − 2 a ) = 1 ÷ a − 2 + (4 ÷ 1 − 4 a )
     Multiply both sides of the equation by: a
     1 − 4 a + (2 ÷ 1 − 2 a ) a = 1 ÷ 1 × 1 − 2 a + (4 ÷ 1 − 4 a ) a
    Remove a bracket on the left of the equation:
     1 − 4 a + 2 ÷ 1 × a − 2 a a = 1 ÷ 1 × 1 − 2 a + (4 ÷ 1 − 4 a ) a
    Remove a bracket on the right of the equation::
     1 − 4 a + 2 ÷ 1 × a − 2 a a = 1 ÷ 1 × 1 − 2 a + 4 ÷ 1 × a − 4 a a
    The equation is reduced to :
     1 − 4 a + 2 a − 2 a a = 1 − 2 a + 4 a − 4 a a
    The equation is reduced to :
     1 − 2 a − 2 a a = 1 + 2 a − 4 a a

    
        a=2
    
    There are 1 solution(s).
