    The modulus is still necessary. Say t=4, then |y| = |-3| = 3.

    It depends on what you're application is, but probably not. Usually you have to split it into two different equations for each absolute value.

    1. (y) = (1-t)
    2. (y) = -(1-t)
    3. -(y) = (1-t)
    4. -(y) = -(1-t)

    Of course, since 1. is the same as 4. and 2. is the same as 3., you only have to do two equations here.

    You end up with y=1-t and y=-(1-t).
