  1. you plug in -8 for r.

    I -15- (-8) l + l -8 l

    l -7 l+ l-8 l

    since you have absolute value bars anything in absolute value turns positive and you take away the bars.

  2. Take the absolute value of -15+8=-7
    absolute value of -7=7
    Add the absolute value of -8 to 7
    the absolute value of -8=8
