Question

What is the What is the value of z in the equation 2(4z − 9 − 7) = 166 − 46? (5 points)19212634

Answer 1

We will have the following:

$\begin{gathered} 2(4z-9-7)=166-46\Rightarrow2(4z-16)=120 \\ \\ \Rightarrow8z-32=120\Rightarrow8z=152 \\ \\ \Rightarrow z=19 \end{gathered}$

So, the value of z is 19.
