Answer 2

Answer:

The value is 99/85

Step-by-step explanation:

Given : a/b = 23

           ( 4a + 7b)/(4a-7b) = ?

Solution : given a/b = 23

               ∴ a = 23b

Substituting the value of a in given equation, we get

( 4a + 7b)/(4a-7b) = (4 x 23b+7b)/(4 x 23b-7b)

                            = (92b+7b)/(92b-7b)

                            = 99b/85b

                            = 99/85
