    2+4z-18

    change it so it's an equation

    2+4z-18=0

    then get 4z alone on one side by subtracting 4z from both sides

    2-18=-4z

    -16 = - 4z

    divide both sides by - 4

    a negative divided by a negative becomes positive

    4 = z

    plug it in

    2+4 (4) - 18

    4x4 is 16

    2+16-18=0

    0=0

    the same can be done for the second one 2+k-8

    make it 2+k-8=0

    move the k to get it alone so subtract k from both sides

    2-8=-1k

    -6 = - 1K

    you can divide by K to make K=6

    plug in 2+6-8=0

    0=0
