$h=15/2$

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 $5$ .

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

$h=15/2$
