------------------------------------------------ Find \( z \) if \( 3z - 19 = 173 \).

Answer :

The given equation is

[tex]3z-19=173[/tex]

First, we add 19 on each side

[tex]\begin{gathered} 3z-19+19=173+19 \\ 3z=192 \end{gathered}[/tex]

Then, we divide the equation by 3

[tex]\begin{gathered} \frac{3z}{3}=\frac{192}{3} \\ z=64 \end{gathered}[/tex]

Hence, z is equal to 64.
