[ 1/1 Equation]
    Work: Find the solution of equation 49.76*(1/x-1/(x+0.8)) = 36 .
    Question type: Equation
    Solution:Original question:
     
1244
25
(1 ÷ x 1 ÷ ( x +
4
5
)) = 36
    Remove a bracket on the left of the equation::
     
1244
25
× 1 ÷ x
1244
25
× 1 ÷ ( x +
4
5
) = 36
    The equation is reduced to :
     
1244
25
÷ x
1244
25
÷ ( x +
4
5
) = 36
     Multiply both sides of the equation by: x
     
1244
25
1244
25
÷ ( x +
4
5
) × x = 36 x
     Multiply both sides of the equation by:( x +
