    I'm dealing with a question where i'm using the following equation:

    q = s / (s+t)

    We know that q = 0.1 and t = 1

    Thus I am trying to rearrange it to get s, I get as far as:

    0.1s + 0.1 = s

    But my maths is rather bad and I do not understand how it then advances to:

    0.1 = 0.9s

    Also what would the algebraic version of this equation to just find t or s?

    Thank you

    Simple enough;
    0.1s + 0.1 = s

    s - 0.1s = 0.1

    0.9s = 0.1

    s = 1/9

    To find t algebraicaly:


    q =s/(s+t)
    s=q(s+t)
    s+t=s/q
    t = (s/q) - s

    What would s equal in terms of t and q? And likewise for t. Thank you very much again.

    q =s/(s+t)
    s=q(s+t)
    s+t=s/q
    t = (s/q) - s
    What s be algebraically? Also if you don't mind if I had this equation instead:

    p = t / (s+t)

    What would s and t equal in this one? Thank you very much! I hope I can grasp this once I see them all.

    q=s/(s+t)
    q(s+t)=s
    q(s+t)-s=0
    qs+qt-s=0
    s(q-1)+qt=0
    s=-qt/(q-1)



    for p=t/(s+t)

    p(s+t)=t
    ps+pt-t=0
    t(p-1)+ps=0
    t=-ps/(p-1)


    s+t=t/p
    s=(t/p) - t
