    geometry question involving triangles

    Hey everyone !

    So my GRE exam is fast approaching

    I am trying to solve the following:

    Triangles PQR and XYZ are similar. If PQ = 6, PR = 4, and XY = 9, what is the length of side XZ?

    I would appreciate any explanation in the *simplest* terms possible !

    Thanks much

    From the given
    \frac{PQ}{PR}=\frac{XY}{XZ}
