Question

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

A.15
B. 17
C.30
D.32

Answer 1

17 is the correct answer

Explanation:

2(2×17-5-3)=166-46

2×60=120

120=120

Hence,

z=17

Answer 2

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 = (136)/(8) \\ z = 17`

Hope this helps
