#h=15/2#

Solve:

#15h+75=25h#

Subtract #75# from both sides.

#15h+cancel75-cancel75=25h-75#

#15h=25h-75#

Subtract #25h# from both sides.

#15h-25h=cancel25h - 75-cancel25h#

#-10h=-75#

Divide both sides by #-10#.

#(-cancel10h)/(-cancel(10))=(-75)/-10#

A negative number divided by a negative number gives a positive result.

#h=75/10#

Both #75# and #10# are divisible by #5#.

#h=(75-:5)/(10-:5)#

#h=15/2#
