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

$\begin{gathered} \frac{3z}{3}=\frac{192}{3} \\ z=64 \end{gathered}$

Hence, z is equal to 64.
