give
[tex]2(4z-6-6)=170-46[/tex]Step 1
a) do the operations inside the parenthesis and do the subtraction in the rigth side
[tex]\begin{gathered} 2(4z-6-6)=170-46 \\ 2(4z-12)=124 \\ \end{gathered}[/tex]b) apply the distributive property to break the parenthesis
[tex]\begin{gathered} 2(4z-12)=124 \\ 8z-24=124 \end{gathered}[/tex]c) add 24 in both sides
[tex]\begin{gathered} 8z-24=124 \\ 8z-24+24=124+24 \\ 8z=148 \end{gathered}[/tex]d) finally, divide both sides by 8
[tex]\begin{gathered} 8z=148 \\ \frac{8z}{8}=\frac{148}{8} \\ z=18.5 \end{gathered}[/tex]therefore, the answer is
18.5
