    Shifting y to 1 side

    Hi,I'm confused as to this equation:

    y=\sqrt{-y+2}

    How exactly can I shift all the variables to 1 side and remove the root?

    If I try multiplying the whole equation by the root, I get a root on the left while if I multiply a root for the 2nd time, I get a root on the right.

    So how exactly can I get rid of the root?

    The way you "get rid" of anything is to do the "opposite". The "opposite" of square root it squaring. Square both sides of the equation.
