Answer:

Step-by-step explanation:

There are two denominators here:  x and 2.  The LCD is 2x.  

Remove the fractions by multiplying all three terms by 2x:

2x(b) + 2x*3/x = 2x*f/2

Reducing these terms, we get:

2xb + 6 = x*f

Grouping the x terms together:  2xb - xf = -6

                                    -6

Solving for x: x = ------------------

                                 2b - f
