h=15/2h=152

Explanation:

Solve:

15h+75=25h15h+75=25h

Subtract 7575 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
