    D = 1/e-f sovle for F, Can someone see if i am correct?

    D = 1/ e - f , solve for F
    is the work and answer
    Multiply each side by e - f then you would have
    d(e-f) = 1
    Then
    Divide by D
    e-f = 1/d
    Then Subtract e
    -f = 1/d - e
    Then multiply each side by -1
    f = (-1/d) + e
    Is this the answer?

    Looks good to me. Probably a good idea not to mix upper-case and lower-case interchangeably throughout your derivations, though. It's clearer if you're consistent that way.

    It's also a good idea to make wise use of brackets. Your working is fine for D = 1/(e-f) but the question reads D = (1/e) - f
