6 - 1/2z = 2/3
subtract 6 from both sides
- 1/2z = -16/3
divide both sides by -1
1/2z = 16/3
rewrite
1z/2 = 16/3
multiply both sides by 2
1z = 32/3
z = 32/3 or 10 2/3
Hope this helps :)

Answer:
x= -3
Step-by-step explanation:
2x+14= 8
2x= -6
x = -3
The answer to this is 90.
(1.)
Would be the correct answer because you can't add the two values together, they both need to have 'x' to be able to.
