See the entire solution process below:

Multiply each side of the equation by $color(red)(-1)$ to solve for $h$ while keeping the equation balanced:

$color(red)(-1) xx 15 = color(red)(-1) xx -h$

$-15 = h$

$h = -15$

To check the solution substitute $color(red)(-15)$ for $color(red)(h)$ in the original equation:

$15 = -color(red)(h)$ becomes:

$15 = -color(red)(-15)$

$15 = +15$

$15 = 15$
