Question

What is the value of z in the equation 2(4z − 9 − 7) = 166 − 46?

19
21
26
34

Please explain how you got the answer do not just put the answer down

Answer 1

Answer: your answer is 19, A

Explanation:

2(4z - 9 - 7) = 166 - 46

2(4z - 16) = 120

8z - 32 = 120

8z = 152

z = 19

So your answer is A. 19

Answer 2

Hi there!

2(4z - 9 - 7) = 166 - 46
let's make this a little more simpler...

2(4z - 16) = 120

use distributive property.
multiply 2 and 4z , 2 and -16.
8z - 32 = 120

add 32 on both sides to isolate the variable

8z = 152

divide both sides by 8...

z = 19

So your answer is A. 19
