    Please help solve this equation?

    Use the following equations to construct an equation for w that involves only the variables a and b.
    A) X*W = Y*T
    B) X/A=B
    C) A^3*y=B
    D) A^2= T*B

    1) w=yt/x

    x=ab
    y=b/a^3
    t=a^2/b

    now put the tree equations above at the first.

    D) A^2= T*B
    W = \dfrac{YT}{X}

    X = AB

    Y = \dfrac{B}{A^3}

    T = \dfrac{A^2}{B}

    Using this sub in the first equation

    W = \dfrac{\dfrac{B}{A^3} \cdot \dfrac{A^2}{B}}{AB}

    I'll leave it up to you to simplify
