    Work: Find the solution of equation (7-10a)/((1.3+a)(2.3+a)) = 0.24 .
    Question type: Equation
    Solution:Original question:
     (710 a ) ÷ ((
13
10
+ a )(
23
10
+ a )) =
6
25
     Multiply both sides of the equation by:((
13
10
+ a )(
23
10
+ a ))
     (710 a ) =
6
25
((
13
10
+ a )(
23
10
+ a ))
    Remove a bracket on the left of the equation::
     710 a =
6
25
((
13
10
+ a )(
23
10
+ a ))
    Remove a bracket on the right of the equation::
     710 a =
6
25
(
13
10
+ a )(
23
10
+ a )
    Remove a bracket on the right of the equation::
     710 a =
