    k = 2 + (1/2) z

    Step-by-step explanation:

    1) Isolate 4k by adding 2z to both sides: 4k = 8 + 2z

    2) Divide all three terms by 4: k = 2 + (1/2) z

    4k-2z=8

    Move - 2z to the other side. Sign changes from - 2z to + 2z

    4k-2z+2z = 8+2z

    4k = 8+2z

    Divide by 4 for 4k and 8+2z

    4k/4 = 8/4 + 2z/4

    k = 2 + 1/2z

    Answer: k = 2 + 1/2z
