2(4z - 3 -1) = 166 - 46

2*(4z - 4) = 120

(4z - 4) = 120/2

4z - 4 = 60

4z = 60 + 4

4z = 64

z = 64/4

z = 16

Answer:

The correct option is 3.

Explanation:

The given equation is


2(4z-3-1)=166-46


2(4z-4)=120

Using distributive property we get,


2(4z)+2(-4)=120


8z-8=120

Add 8 on both the sides.


8z=120+8


8z=128

Divide both sides by 8.


z=16

The value of z is 16, therefore the correct option is 3.
