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#
