can you guys please help me on change of subjects?

V^2(squared)=U^2+2as make u the subject

V^2=u^2+2as make s the subject

mc^2=p make c the subject

p^2=4m^2/x make x the subject

r/st= w/x^2 make x the subject

    v^2 = u^2 + 2as

    v^2 - 2as = u^2

    sqrt(v^2 - 2as) = sqrt(u^2)

    sqrt(v^2 - 2as) = u

    v^2 = u^2 + 2as

    v^2 - u^2 = 2as

    (v^2 - u^2)/2a = s

    mc^2 = p

    c^2 = p/m

    sqrt(c^2) = sqrt(p/m)

    c = sqrt(p/m)

    p^2 = 4m^2/x

    xp^2 = 4m^2

    x = 4m^2/p^2

    r/st = w/x^2

    rx^2/st = w

    x^2/st = w/r

    x^2=stw/r

    sqrt(x^2) = sqrt(stw/r)

    x = sqrt(stw/r)

    V^2(squared)=U^2+2as make u the subject

    V^2-2as = U^2

    square root of V^2 -2as = U

    ......................

    p^2=4m^2/x

    divide both sides by 4m^2

    p^2/4m^2 = x
