Question

What is the value of z in the equation 2(4z − 5 − 3) = 166 − 46?

Answer 1

Answer:

17 is the correct answer

Step-by-step explanation:

2(2×17-5-3)=166-46

2×60=120

120=120

Hence,

z=17

Answer 2

Answer:

17

Option B is the correct option.

Solution,

$2(4z - 5 - 3) = 166 - 46 \\ or \: 8z - 10 - 6 = 120 \\ or \: 8z - 16 = 120 \\ or \: 8z = 120 + 16 \\ or \: 8z = 136 \\ or \: z = \frac{136}{8} \\ z = 17$

Hope this helps
