    Combining like terms is combining numbers with the same variables.

    = - 14 + 12 + 9z - 16z

    = (-14 + 12) + (9z - 16z)

    = - 2 - 7z

    ~Put into standard form

    -7z - 2

    -6/7

    Step-by-step explanation:

    -14+12+9z-16z=0

    -6-7z=0

    Add 7z to both sides

    -6=7z

    Divide both sides by 7

    z=-6/7

    Therefore the value for z is - 6/7
