Question

What is the value of z in the equation 2(4z − 3 − 1) = 166 − 46? 14 15 16 17

Answer 1

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 2

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.
