# How do you solve and check your solutions to 15=-h?

See the entire solution process below:

#### Explanation:

Multiply each side of the equation by $\textcolor{red}{- 1}$ to solve for $h$ while keeping the equation balanced:

$\textcolor{red}{- 1} \times 15 = \textcolor{red}{- 1} \times - h$

$- 15 = h$

$h = - 15$

To check the solution substitute $\textcolor{red}{- 15}$ for $\textcolor{red}{h}$ in the original equation:

$15 = - \textcolor{red}{h}$ becomes:

$15 = - \textcolor{red}{- 15}$

$15 = + 15$

$15 = 15$
