Answer:

-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

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

Best of Luck!
