    a=b(1/c - 1/d)

    a = b/bc -b/bd.. step 1

    distribute b to the other fractions:

    a= b/bc - b/bd

    then add b/bd to both sides:

    a + b/bd = b/bc

    then divide by b on both sides:

    (a + b/bd) / b = bc

    then divide again by b on both sides:

    ((a+ b/bd) / b) / b) = c
