Question

Variables review find z if 3z-19=173

Answer 1

The given equation is

`3z-19=173`

First, we add 19 on each side

`\begin{gathered} 3z-19+19=173+19 \\ 3z=192 \end{gathered}`

Then, we divide the equation by 3

`\begin{gathered} (3z)/(3)=(192)/(3) \\ z=64 \end{gathered}`

Hence, z is equal to 64.
