solve for "y"

  • algebra 1 - ,

    Please change your screenname, it is just a little presumptious that somehow you should go to the head of the line.

    is the left side

    1/(a-y) or (1/a) - y ?

  • algebra 1 - ,

    If it is 1/(a-y) = 1/y

    then cross multiply to get y = a -y

    solve for y in terms of a.

  • algebra 1 - ,

    cross multiply is a very dangerous term for beginning students. Change your thinking to

    multipy both sides by y then
    multiply both sides by a-y
    giving
    y=a-y
    then add y to both sides
    2y=a
    divide both sides by 2
    y=a/2
