# How do you solve 6z - 10- z + 5= 0?

Jun 24, 2017

z = 1

#### Explanation:

1. Combine like terms.

$\textcolor{red}{6 z} \textcolor{b l u e}{- 10} \textcolor{red}{- z} \textcolor{b l u e}{+ 5} = 0$
$5 z - 5 = 0$

2. Add 5 to both sides to isolate the variable ($z$).

$5 z - 5 + 5 = 0 + 5$
$5 z = 5$

3. Divide both sides by 5 to find $z$.

$\frac{5 z}{5} = \frac{5}{5}$

$z = 1$
