Verified Answer :

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.

Step-by-step 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.
