# How do you solve 15z=25?

Feb 23, 2017

See the entire solution process below:

#### Explanation:

Divide each side of the equation by $\textcolor{red}{15}$ to solve for $z$ while keeping the equation balanced:

$\frac{15 z}{\textcolor{red}{15}} = \frac{25}{\textcolor{red}{15}}$

$\frac{\textcolor{red}{\cancel{\textcolor{b l a c k}{15}}} z}{\cancel{\textcolor{red}{15}}} = \frac{5 \times 5}{\textcolor{red}{5 \times 3}}$

$z = \frac{\textcolor{red}{\cancel{\textcolor{b l a c k}{5}}} \times 5}{\textcolor{red}{\cancel{5} \times 3}}$

$x = \frac{5}{3}$
